FIELD: instrument engineering.
SUBSTANCE: submarine emulator includes a receiver-amplifier channel, an incoming signal angle detection unit, memory circuit, frequency curve correction circuit, and transmitting channel, connected in series. Besides, the submarine emulator includes phase curve correction circuit between the frequency curve correction circuit and the transmitting channel. The control circuit input is connected to the output of the incoming signal angle detection circuit, and the output is connected to the inputs of the frequency and phase curves correction circuits.
EFFECT: enhancement in believability of the echo signal imitation in relation to the signal target-deflection angle.
