Abstract:
1. A bistatic azimuth detection system comprising: sound source equipment which transmits a sound wave to a target and transmits first position information on the sound source equipment; wave receiving equipment which transmits second position information on the wave receiving equipment with a received wave signal which is obtained by receiving a direct wave from the sound source equipment and a reflective sound from the target; sound source azimuth detection means which detects an azimuth of the sound source equipment viewed from the wave receiving equipment on the basis of the first and second position information; calculation means which detects a sound source arrival azimuth, which is an arrival azimuth of the direct wave from the sound source equipment, and a target arrival azimuth, which is an arrival azimuth of the reflective sound from the target, on the basis of the received wave signal, to calculate difference between them; and target azimuth detection means which detects an azimuth of the target on the basis of the azimuth detected by the sound source azimuth detection means, and the difference calculated by the calculation means.
