Claims

[Scope of utility model registration request]

Underwater detection transmitting/receiving means for emitting ultrasonic waves vertically downward and in the diagonal directions of the left and right sides of the ship and receiving the reflected sound; and a separation circuit that separates the received signal from the port side oblique direction and the received signal from the starboard side oblique direction; and detects a seabed reflection signal from the port side oblique direction received signal from the separation circuit. , a port side seabed signal detection circuit that performs waveform shaping on the seabed reflected signal, performs distance correction for the oblique angle, and provides a predetermined delay time; a starboard side seabed signal detection circuit that detects the signal, performs waveform shaping, performs distance correction for the oblique angle on the seabed reflected signal, and provides a predetermined delay time; and a vertically downward received signal from the separation circuit. , a synthesis circuit for synthesizing a port side submarine signal from the port side submarine signal detection circuit and a starboard side submarine signal from the starboard side submarine signal detection circuit;
An underwater detection display device comprising: a fish detection recorder for recording signals from the synthesis circuit.
