Abstract

PURPOSE: To improve a display speed by making the generation speed of a slope wave, which controls deflection of the electron beam in a rader unit, etc., fixed and by reading out video signals from a shift register with read clock signals of this period.
CONSTITUTION: A radar trigger signal is inputted to X.Y deflection signal generator 2 through input line 1, and simultaneously, a radar video signal is inputted to AD converter 10 through input line 9 and is stored in shift registers 11aW11n. Data of respective registers are read out successively by clocks 17aW17n from generator 14. Here, the X.Y deflection signal from generator 2 generates a slope wave in a fixed speed independently of the radar range switching signal, and signals 17aW 17n are generated synchronously with the radar trigger input signal. Read video data are subjected to D/A conversion in 19 through OR circuit 18 and are supplied to the cathode of cathode-ray tube 7 after amplification in 20.
