Abstract
A radar receiver includes a bank of matched filters for use in processing return signals received from a remote target. In some embodiments, the radar receiver is capable of generating accurate estimates of target range and range rate based on returns from a single transmitted pulse having a low time-bandwidth product. In at least one embodiment, a computationally efficient interpolation technique is used to generate an estimate of an actual target Doppler frequency based on output signals of the bank of matched filters.
