Abstract
A doppler radar system comprises a solid state microwave source which is pulsed on and off with a duty cycle typically around 10.sup.-3. The microwaves are transmitted towards a nearby target with a small amount supplied to a mixer also supplied with signals received from the target. The mixer output is passed through a gate opened in coincidence with the mixer pulsed output, and supplied to an integrator whose output forms a doppler signal representing target velocity. Target directionality is found by providing two channels fed in quadrature phase.
