Zusammenfassung:	STABILIZED DIGITAL PPI RADAR SYSTEM A radar system having the radar pulse rate controlled directly from an indicator unit. Separate modulator-trans-mitter-receiver and digital video processor indicator units are provided. A radar trigger pulse is produced by the processor unit in synchronism with the processor clock at a rate determined by the radar range setting. An acknowledge signal is produced in turn by the modulator-transmitter-receiver in accordance with an activating signal in the modulator and fed back to the indicator unit to start video signal digitization and the CRT sweep. Jitter between the start of the radar return signal and the radar sweep are eliminated.
