探知信号の経時表示装置。[Claims for Utility Model Registration] An underwater detection signal time-lapse display device that extracts detection signals of a detection direction θ and a tilt angle ψ from an underwater detection sonar device and displays them over time, comprising: a second storage circuit, and the extracted detection signal is alternately switched and guided to the first and second storage circuits for each wave transmission (the first switching means and the signal to the first and second storage circuits are connected to the first and second storage circuits); a main memory having a capacity of m rows and n columns; means for leading to the main memory; a setting device for setting depth XD and traveling distance YD for display; a speedometer for measuring ship speed V; and a means for leading to the main memory from the first or second storage circuit. When the address for writing is X in the row direction and Y in the column direction, Y... Embroidery → Hekisatsu Kano a second switching means that switches and connects the main memory and the erase signal generation circuit for a certain period of time either before or after writing to the main memory based on the above formula (1); If cosθ≧0 within a certain period of time, the above (1)
The above erase signal is written in one column of the column address determined by substituting (m-1) into X in the equation, and when csoθ is 0, the erase signal is determined by substituting 0 into X in equation (1) above. an erase signal write circuit that writes the erase signal to one column of the column address; a read circuit that reads the stored contents of the main memory in an X-Y raster scanning method; and a read circuit that transmits the read signal to the read circuit. A device for displaying underwater detection signals over time, comprising a corresponding display in synchronized X-Y raster scanning.
