ABSTRACT:
A continuous wave frequency modulated signal is radiated from a range rate measuring system and returned by a target, the range rate of which, relative to the measuring system, is to be determined. The radiated signal and return signal are mixed to produce a beat frequency signal which is converted to a square wave signal marking passage of the beat frequency signal above and below its average value. A detector produces signals indicative of the presence and absence of transitions of the square wave signal at the turnaround points of the modulation waveform. The range rate of the target is directly related to the rate of the presence and absence of such signals.
