Abstract
An underwater detecting device which performs direction detection covering a wide range in the underwater in a short period of time and indicates an object to be detected in motion by the use of different colors corresponding to the speeds of the object. An underwater detecting device of this invention is composed of: ultrasonic wave transmission means (101) to emit detection pulse signals of a fixed carrier-frequency in the directions covering a wide-range; ultrasonic wave receiving means (1p, 1q) performing detection in different directions in a wide range one after another and receiving, at least twice, ultrasonic wave signals coming from the directions in a wide range; phase difference detecting means (10, 12) for detecting a phase difference between carrier waves of received signals coming from the same direction in a wide range and caught by wave receiving means; computing means (18) for computing an angular frequency on the basis of the phase difference between the carrier waves; color signal generating means (103) for emitting a specified color signal corresponding to the angular frequency on the basis of a signal indicating the angular frequency and emitted by said angular frequency computing means; and indication means (104) for indicating an output signal emitted by said color signal generating means.
