Abstract:
A pulse radar system comprising:(a) a tuned magnetron;(b) an input feeding voltage to said tuned magnetron;(c) a modulator connected to said magnetron for pulsing a feeding voltage to said magnetron;(d) a circulator connected to said tuned magnetron;(e) a low power microwave signal source radiating signals of frequencies fixed during each period of magnetron pulse repetition and differing from frequencies of correspondent signals generated by said magnetron and said source connected to said magnetron through said circulator to send signals to said magnetron in pauses between pulses of said magnetron;(f) a signal converter connected to said modulator, to said circulator and to said microwave signal source to receive signals from said low power microwave signal source after said signals are reflected by said magnetron and to convert said signals into signals connected in time to moments in which frequencies of said low power source and an oscillating frequency of said magnetron coincide, and to trigger said modulator.
