Abstract:
1. A method for estimating information about a remote target using reflected energy in a radar system, the method comprising: receiving a return signal at a receiver of the radar system, the return signal resulting from a single transmitted pulse reflecting off the remote target; applying the return signal to a bank of matched filters of the radar system, wherein different matched filters in the bank of matched filters are tuned to different Doppler frequencies; selecting, by a signal processor of the radar system, a matched filter having a highest output signal magnitude from the bank of matched filters, the selected matched filter being tuned at a first Doppler frequency; interpolating, by the signal processor, an estimate of an actual Doppler frequency of the remote target based, at least in part, on the first Doppler frequency associated with the selected matched filter; determining an estimated range rate of the target based, at least in part, on the estimate of the actual Doppler frequency of the target; and providing the estimated range rate of the target to at least one of a user interface and a network interface of the radar system.
