The target detections that initiate a track must take advantage of whatever gains are possible in SNR, because viable radar systems must operate at very low false-alarm rates. Making use of doppler information is a crucial way of increasing the SNR. Once a track has been initiated, a variety of methods of increasing sophistication are possible to retain the track. All of them run into trouble as tracks become more complicated and the radar environment becomes more congested.
