Abstract
1289584 Pulse radar FERRANTI Ltd 19 April 1971 [14 March 1970] 12361/70 Heading H4D Radar echo, bearing and marker data are recorded on a video tape recorder in the form illustrated in Fig. 2 where 20 represents a pulse synchronous with radar pulse emission, 21 the echo video signal, 22 and 24 framing start and end pulses and 23 bearing and marker data bits. In the apparatus, Fig. 1, a delay unit 10 ensures that there is no overlap with the synchronous pulse and after an adjustable delay 12 (corresponding to maximum radar range) a switch 11 connects the output of a modulator 17 to the recorder. Bearing information is passed to a digital encoder 18 which is connected to a register 14 via a counter 13. Playback.-Appropriate switching circuits to separate the various signals are described, Figs 3, 4 (neither shown).
