The receiver described here can estimate either the frequency or the AOA (Angle of Arrival) of radar emitters with respect to their PRFs using information embedded in the cross-correlation of signals obtained from three data channels that are delayed replicas of each other. Using cross-correlation data removes the Radio Frequency (RF) carrier and allows much slower sampling rates in generating two complex time series. This approach is sufficiently robust that over 2 GHz of RF bandwidth can be processed using less than a one MHz sampling rate for the digital signal processor, which permits applying higher resolution encoders for enhanced dynamic range.
