Circuits for a Pulsed Doppler Radar

Abstract

The report describes in detail the circuitry of a multirange-gate pulse doppler radar which operates at 400 MHz. The system is a low power one that generates only a one-watt (peak) pulse of 50 ns length at a 40 kHz rate, for an average power of 2 mW. The receiver employs RF amplification, a wide-band video amplifier following the coherent mixer, a set of boxcars used as range gates, and active high-pass filters which are voltage adjustable. The timing circuit required is discussed.
