range bins containing targets already in track, averaging over enough range bins

to minimize any unknown target influences, prescreening the data for large
amplitudes that might indicate a target, or other means. Many of the required
techniques are similar to those used in constant false alarm rate detection,
discussed in Chap. 6.
DPCA is a clutter suppression technique, and as such it makes sense to
apply it only on the Doppler bins in the clutter region. It is easy to see that if the

interference is noise-limited the adaptive DPCA operation reduces to
performing no operation (see Prob. 36). Consequently, DPCA should not be
applied in the clear region of the Doppler spectrum.
