Abstract
A Doppler matched binary pulse compressor having means to initiate operation, means to generate a Doppler matched filter bank, means to compress the pulses from the Doppler matched filter, either linear or soft limited, means to estimate the signal phase in real time and means to select overall optimal filters in real time. The foregoing includes a phase estimator having a quadrant detector and means to scale the quadrature components while preserving the signal phase, means to reduce accuracy computations to 45.degree. or less of the first quadrant, and means to reconstruct the phase to place the signal in the proper quadrant.
