ABSTRACT:
A decimating digital PN receiver (10) processes a target return signal. The target return signal is decimated (34) processed at a slower speed. The decimated target return signal is then digitally correlated (28). The correlated signal is digitally filtered (30) and a fast Fourier transform (32) is applied to produce the output (33).
