Abstract : Described is a method for determining doppler frequency by the measurement of the maximum pulse-to-pulse difference over one doppler cycle. A box-carred (sample-and-hold) phase detector's output is differentiated to obtain pulses whose amplitude represents the amplitude of individual boxcar transitions. The largest pulse amplitude is selected for indication of doppler frequency. (Author)
