ニングソナー。a compass that generates a true bearing signal indicating the true bearing of the ship;
a tracking azimuth indicator that generates a specified tracking azimuth signal; a transducer rotating mechanism that rotates the transducer and generates a transducer azimuth signal indicating the azimuth of the transducer; and a true azimuth signal from the compass. and the tracking azimuth signal from the tracking azimuth indicator and the transducer azimuth signal from the transducer rotation mechanism, and determine whether the difference between the true azimuth signal and the transducer azimuth signal is the true direction, the position signal and the tracking azimuth. An azimuth tracking type scanning sonar comprising: an azimuth control device that generates an azimuth control signal that rotates a transducer/receiver rotation mechanism to match the difference between the signal and the transducer rotation mechanism.
