ABSTRACT:
This system is directed to an acoustic target simulator for use with active nd passive sonar systems. A receiver and a transmitter are mounted on the front and rear of the simulator. Separate high frequency channels are provided for the front transmitter and receiver and for the rear transmitter and receiver. The simulator utilizes a selector circuit that is operative upon receipt of a signal from one receiver-transmitter channel to disable the second receiver-transmitter channel. The simulator also includes a sonar becon which provides tracking capability for low-frequency sonars and an evasive action circuit which operates upon receipt of certain signals to disable the system.
