The form of the deep-bomb array is used as a result of deep-bomb arrangement, directly influences whether an incoming torpedo passes through the array, determines the array effect of the deep-bomb array, and finally influences the interception effect of the deep-bomb on the incoming torpedo. Therefore, measuring the distance between adjacent landing points of the deep-ammunition array becomes an important content affecting the evaluation of the ammunition array effect and the evaluation of the deep-ammunition combat effect.
At present, measurement of the arrangement effect of the suspension type deep-ejection array is blank, and a measurement method of the spacing distance between adjacent landing points of the ejection array has not been reported in detail. Under the offshore test condition, the measurement method and means are limited, the test environment condition is far from the laboratory and the land test condition, and the measurement is difficult.

The requirements of the function, performance, structural design and volume and weight of the deep projectile determine that the deep projectile is difficult to carry a GPS module under enough conditions, and the positioning of the offshore test is difficult. In the test process, after the ammunition is launched into water, the drop point of each ammunition entering water can also drift under the influence of factors such as the flow velocity of water flow, and the position of the drop point is more difficult to measure.
(2) The offshore environment is complex and the state is difficult to maintain.
The offshore test needs to face complex offshore environments, such as wind direction, wind speed, water flow velocity and the like, and can have deviation influence on the drop point position of each deep bomb in the bomb array; meanwhile, great difficulty is brought to the state of the drop point position and the maintenance of the state of the spring array, and the difficulty of measuring the drop point position is greatly improved.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
The invention provides a method for measuring the distance between adjacent landing points of a suspended deep-bomb array under the offshore environmental condition, which is suitable for evaluation of the array effect of the suspended deep-bomb array and the operational use research of the suspended deep-bomb.
Under the offshore test condition, the sea condition is not higher than three stages, a water surface ship with a certain displacement is selected as a transmitting platform, and transmitting equipment is installed. And (3) transmitting the suspension type deep-bomb arranging bomb array to the appointed water area by utilizing a transmitting platform in a certain sea area, and measuring the interval distance between two adjacent deep bombs of the bomb array. The ammunition launching device can be a prototype which is installed or consistent with the installation state, and the deep ammunition is launched according to the installation launching process. The method comprises the following specific steps:
(1) Reference area selection and placement
The distance D between the position of the deep-bomb arranging center point and the position of the launching platform is determined, two rows of buoys are longitudinally and longitudinally symmetrically arranged around the deep-bomb arranging center point, the spacing distance between the two rows of buoys is L, the actual falling point position is generally not more than 3 times of the error range of the theoretical falling point position according to the error normal distribution rule, the longitudinal scattering error calculation of one time of extension outside the buoys is considered, and the longitudinal scattering error of the deep-bomb with the spacing distance of about 3-5 times is obtained. The number of the buoys in each row is m, and the transverse interval distance and the longitudinal interval distance of the buoys are kept consistent; the width of the accumulated covering transverse distance of the m buoys is L x (m-1), the covering width of the deep-elastic array is required, and 20% of the extending array width at the two ends is used as the transverse covering allowance. As shown in fig. 1. Weights can be added below each buoy, so that drift caused by ocean current factors is reduced.
(2) Drop point position parameter measurement
The launching device carries out the calculation of the launching parameters according to parameters such as the deep-ammunition array laying distance D and waits for ammunition to be launched.
The aerial unmanned aerial vehicle flies to the position of the bullet array laying center point to be above, hovers by a certain height, and covers and aims at the buoy reference object area to take a photograph by adopting a overlooking angle.
And the launching device implements deep-bullet launching according to the calculated launching parameters. After the deep-bullet launching and the array arrangement are finished, the aerial photo unmanned aerial vehicle is recovered, the shooting content is played back, and the shooting lens at the moment of entering water of each deep bullet is subjected to screenshot and numbering preservation in sequence.
(3) Measuring and calculating distance between adjacent falling points
The numbered shots are processed separately as shown in fig. 2. And connecting the position points of the buoys in each figure to form a coverage grid. The lowest left column buoy is selected as an origin, an X-Y coordinate system is established by taking the row buoy as an X axis, namely the X axis is the vertical direction of the forward route of the incoming torpedo and coincides with the row buoy, and the Y axis is the opposite direction of the forward route of the incoming torpedo. The falling point position B is perpendicular to the X axis and the Y axis of the coordinate system, and the intersection point with the Y axis is marked as B 1y 、B 2y …B ny The intersection with the X-axis is marked B 1x 、B 2x …B nx . The length between each falling point position point and the intersection point of the falling point position point and the Y axis and the X axis is measured in the figure. I.e. the projection lengths of the falling point positions on the X axis and the Y axis are respectively B 1 B 1y 、B 2 B 2y …B n B ny ，B 1 B 1x 、B 2 B 2x …B n B nx Respectively corresponding records according to rectangular coordinate system counting rulesIs l 1x 、l 2x …l nx ，l 1y 、l 2y …l ny 。
The projection length of a drop point position on a coordinate axis can be measured in each picture, and the interval length between different drop points in the picture can be directly calculated by using the coordinate parameters because the coordinate systems established in different drop point screenshots are the same. As shown in FIG. 2, the interval length 1 between two adjacent falling points of the matrix in the graph in the coordinate system can be obtained 1 、1 2 …1 (n-1) The method comprises the following steps:
1 1 ＝((l 2x -l 1x ) 2 +(l 2y -l 1y ) 2 ) 1/2
……
1 (n-1) ＝((l nx -l (n-1)x ) 2 +(l ny -l (n-1)y ) 2 ) 1/2 (1)
Meanwhile, three groups of data of the interval distance length of the two buoys are measured on the graph, and an average value is calculated and recorded as l.
Because the deep-flick drop point and the reference object buoy are both obtained by taking a picture of the screenshot through the aerial unmanned aerial vehicle, according to the proportional relation between the position relations in the same reference system, the distance between the drop points in the screenshot is longer (1 1 ，1 2 …1 (n-1) ) Proportional relation to the reference object spacing distance length (L) and actual falling point spacing measurement distance (L 1 ，L 2 …L (n-1) ) The proportional relation of the distance (L) between the two reference objects is consistent. This can be achieved by:
1 1 /1＝L 1 /L,
……
1 (n-1) /1＝L (n-1) /L。
the distance between two adjacent falling points is obtained as follows:
L 1 ＝L×1 1 /1，
……
L (n-1) ＝ L×1 (n-1) /1. (2)
(4) Array type parameter measurement and evaluation
From the principle of deep-bomb defense, the action of the bomb array mainly depends on the projection area of the bomb array on the torpedo forward path. The projected area is mainly represented by a horizontal projected length and a vertical projected length. The horizontal projection length determines the azimuth coverage of the torpedo relative to the platform, the vertical projection length determines the coverage of the torpedo navigation depth, and the vertical projection length is generally 2 times of the deep-bomb damage radius, namely 2r. As can be seen from fig. 1 and fig. 2, the horizontal projection of the distance between adjacent landing points in the spring array is the projection of the distance between adjacent landing points in the horizontal direction, i.e. on the X-axis.
Referring to FIG. 2, the position of the falling point measured in the step (3) is shown as the length l between the falling point and the intersection point of the coordinate axes 1y 、l 2y …l ny And l 1x 、l 2x …l nx Projection distance L between two adjacent falling points in horizontal direction of incoming target x1 、L x2 …L xn The relation of (2) is:
(l 2x -l 1x )/l＝L x1 /L
……
(l nx -l (n-1)x )/l＝L x(n-1)/ L
obtaining the projection distance L of the spacing distance between every two adjacent landing points in the horizontal direction x1 、L x2 …L x(n-1) 。
L x1 ＝L×(l 2x -l 1x )/l
……
L x(n-1) ＝L×(l nx -l (n-1)x ) /l (3)
And solving the sum of the lengths of the projections of the falling points in the bullet array in the horizontal direction.
Firstly, judging whether the projection length value of the interval distance between every two adjacent landing points in the horizontal direction reaches 2 times of the deep-ejection damage radius. If the projection length is not less than 2 times of the damage radius of the deep projectile, the projection length in the horizontal direction is 2 times of the damage radius; if the projection length is smaller than 2 times of the damage radius of the deep projectile, the projection length is directly taken. Summing the values to obtain the interception range of the deep-ejection array in the horizontal directionGirth value L x-all 。
If L x(n-1) Not less than 2r, L x(n-1) ＝2r，
L (x-all) ＝L x1 +L x2 +…+L x(n-1) ；
If L x(n-1) ＜2r，
Then L is (x-all) ＝L x1 +L x2 +…+L x(n-1) (4)
From solved L (x-all) The length of an interception area formed by the deep-bomb array on the incoming torpedo forward route can be judged.
The invention provides a method for measuring the distance between adjacent landing points of a suspension type deep-bomb array under the offshore condition. The method provides support for evaluation of the deep-bomb array effect, and lays a foundation for evaluation of the combat use and combat effectiveness of the deep bomb.

In order to simplify the processing flow, the heading of the test ship is adjusted to be north, and the distance D between the center point and the point A of the deep-bomb array is 1200m. And arranging 2 rows of buoys at the front-back symmetrical positions of the deep-bomb arranging center point in the direction perpendicular to the incoming torpedo way. The static longitudinal dispersion error of the deep spring is about 11 meters at 1200 meters, and the distance between each two buoys in the same row is selected to be L=50m. The width of the deep-spring array is required to be about 280m at 1200m, so that a plurality of buoys can be accumulated to cover the width of the transverse distance by about 380m, and the buoys are distributed at intervals of 50m, and 8 buoys are distributed in each row. Namely 16 buoys are distributed in two rows, 8 buoys are distributed in each row, and the inter-row spacing and the intra-row spacing are 50m.
(2) Drop point position parameter measurement
The launching device carries out the calculation of the launching parameters according to parameters such as the deep-ammunition array laying distance D and waits for ammunition to be launched.

And the launching device implements deep-bullet launching according to the calculated launching parameters. After a group of deep shots are launched, the aerial photo unmanned aerial vehicle is retracted, the shot content is played back, and the shot shots and the numbers of the shot shots at the moment when each deep shot enters water are sequentially stored.
(3) Measuring and calculating distance between adjacent falling points
And respectively processing the numbered screenshots. And connecting the position points of the buoys in the diagram to form a coverage grid, and selecting the position of the buoy at the lower left corner as an origin to establish an X-Y coordinate system. From each falling point position B n Perpendicular to the X-axis and Y-axis of the coordinate system, and B is measured in the figure 1 B 1y 、B 2 B 2y …B n B ny The length value of (2) is denoted as l 1x 、l 2x …l nx The data are filled in the X-axis projection length of the data line in the table 1; measurement B 1 B 1x 、B 2 B 2x …B n B nx The length value of (2) is denoted as l 1y 、l 2y …l ny The method comprises the steps of carrying out a first treatment on the surface of the The data is filled in the data line "Y-axis projection length" in Table 1.
From (1), the adjacent drop point interval length value of 1 can be obtained 1 ，1 2 …1 (n-1) The data line "adjacent drop interval length" of table 1 is filled.
Three sets of two buoy interval length data were measured on the graph and averaged and recorded as l=1.82 cm.
From (2), the actual spacing distance L between adjacent landing points can be obtained 1 ，L 2 …L (n-1) The data line "adjacent drop point spacing distance" of table 1 is filled.
TABLE 1A group of bullet array drop point data measurement record table
(4) Array type parameter measurement and evaluation
Combining (3) and data l measured in the preceding step 1x 、l 2x …l nx And l 1y 、l 2y …l ny The method comprises the steps of carrying out a first treatment on the surface of the Calculating the projection distance L of the spacing distance between every two adjacent landing points in the horizontal direction x1 、L x2 …L x(n-1) The data are recorded in the data line "X-axis projection spacing distance" of Table 1.
According to the two rows of data of the X-axis projection length and the Y-axis projection length in the table 1, each falling point is drawn in a rectangular coordinate system, and an array schematic diagram is formed and is shown in fig. 3.
The damage radius r=14m of the small-caliber suspension type deep projectile can judge that the projection distance of the spacing distance between partial adjacent landing points in the horizontal direction is larger than 2r according to the calculated data, and the partial data is replaced by a 2r value. According to (4), obtaining the length value L of the interception range of the bullet array (x-all) ＝234m。
Because the deep bullets at the two top ends of the bullets array respectively have a half circular coverage area which is not included in the projection length calculation, the effective action range of the whole bullets array needs to be extended outwards by a damage radius which is L (x-all)+ +2r＝234m+28m＝262m。
In summary, the method for measuring the position of the deep-flick water moment and the interval distance between adjacent landing points is provided under the offshore test condition, the set buoy reference is utilized to dynamically change along with the ocean environment, the change rule of the buoy reference and the position of the landing points is kept consistent, and the unmanned aerial photography mode is adopted to measure the position of the ammunition landing points and the interval distance between the adjacent landing points at the water moment, so that the deep-flick array shape is evaluated, and the efficacy evaluation and the operational use research of the suspended deep flick are supported.
