置。In a sonar display device that simultaneously displays the received signal of one sonar on at least one of the PPI or B scope and the A scope, the threshold level is determined by measuring the threshold level applied to the P-circle or B-1 display video signal. A circuit that outputs a signal representing the threshold level, and a circuit that outputs a signal representing the
Equipped with a circuit that superimposes one display signal on a time-division basis.
A sonar display device characterized in that a threshold level applied to the display video signal is displayed on an A-scope.
