Abstract
A radar system (10) forms a range-Doppler map (28). A CFAR processor (57) determines a threshold (60) and evaluates the map (28) to identify potential targets whose amplitudes are greater than the threshold. The potential targets are evaluated to determine (88) whether they form substantial peaks for the Doppler bins (32) where they are located, and to determine (98) whether they resemble noise more than targets. In addition, the potential targets are evaluated to determine (114) whether they are most likely the result of range sidelobes and to determine (118) whether they are most likely images of targets rather than targets. When any of these situations are detected, the potential targets are removed from a potential target list (50).
