Beschreibung
Zusammenfassung:	radio navigation, short-range radio navigation of aircraft, radio beacon landing systems of centimeter range. SUBSTANCE: given detector has intermediate frequency amplifier, amplitude detector, gate generator, three pulse formers, three amplifiers-limiters, three reversible counters, two RS flip-flops, D flip- flop, clock pulse generator, eight AND gates, two OR gates, two threshold units, inverter and differentiation circuit. Achievable technical result of invention consists in possibility of detection of intraray interference echoes by sigh of accompanying angular modulation with various ratios of initial phases of signal and echo under conditions of a priory unknown Doppler frequency drift and instability of frequencies of transmitter and heterodyne of receiver. EFFECT: improved functional potential of detector. 2 dwg
