Description
加えて、第1直接波26、第1間接波27、第2直接波28、第2間接波29の組み合わせにおいて、実在する物体であるかゴーストであるかの区別ができない複数の組み合わせが可能である場合には、車両30に対して最も近い位置を算出する第1直接波26と第1間接波27の組み合わせを採用している。ゆえに、車両30が接触するおそれの高い物体の位置を検知しない事態を防ぐことができる。
・上記実施形態では、第1物体50a及び第2物体50bの位置を検出するものとしているが、第1物体50a及び第2物体50bに加えて、車両30から第2物体50bよりも遠方に位置する第3物体の位置をも算出するものとすることもできる。この場合には、第3物体が反射した反射波を、第3直接波、第3間接波として受信するものとする。
Claims (1)
