Abstract
A trawl net () is attached to ends of warps () extending from a ship (), such as a trawl boat, in the sternward direction, and a transponder () to transmit a response signal is attached to an upper part of a net mouth of the trawl net (). The ship () forms a transmission beam TB of a detection signal by a transducer () at the bottom of the ship, and performs detection in the detection range. The transponder () receives the detection signal, and forms a transmission beam TPB of a frequency different from that. A detection image and a position display image of the transponder are superposed and displayed on a display of a scanning sonar or are displayed side by side.
