In this chapter, after briefly examining the problem, we will be introduced to two highly effective techniques for detecting such targets. One is called Classical DPCA, for displaced phase center antenna. The other and newer technique are called notching or clutter nulling. We'll take up Classical DPCA first; then, notching; and, finally, a combination of the two. In closing we'll touch on the adaptation of these techniques to precise angle measurement.
