Claims

[Scope of utility model registration request]

In a sonar that detects underwater objects by sending out ultrasonic waves in a desired direction, a processing system configured to display a detection signal containing information as a PPI on one area set on the image screen of a cathode ray tube, and on the other side. A processing system configured to be displayed as a cross-sectional figure is alternately switched in the area of . A transducer that transmits ultrasonic waves in a horizontal direction or a direction tilted at a certain angle and receives a returning information signal; and a transceiver that is connected to the rear stage of the transceiver through one contact of a changeover switch, and the transceiver a first memory circuit in which the transmitted information signal is stored;
The signal read out from the first memory circuit is composed of a cathode ray tube or the like that is displayed in PP mode, and the processing system that displays it as a cross-sectional figure sequentially displays the depression angle of the handset at each preset angle. The depression angle control circuit is connected to the other contact of the changeover switch and the depression angle control circuit is switched under the control of the pulses of the control circuit. Corresponds to (,
a second memory circuit group connected to each contact of the switch; an output signal switch to which the output of the second memory circuit group is applied; and the control circuit. a cross-sectional position controller that is controlled by and sends a pulse for controlling the cross-sectional position to the second memory circuit group; and the first It is composed of a memory circuit and the cathode ray tube connected to the rear stage of the first memory circuit, and the cathode ray tube is of a raster scanning type, and its deflection coil is driven by a signal from the control circuit. The output of the television circuit is applied, and the image plane of the cathode ray tube is divided into two areas, and is configured such that a PPI image is displayed in one area and a cross-sectional image is displayed in the other area. A sonar display device featuring:
