Space Time Adaptive Processing (STAP) Radar
Abstract
In previous chapters, the use of Doppler processing was discussed as a key method to discriminate both in distance and velocity. Discrimination in direction (or angle of arrival to the antennas) is provided by aiming the radar signal, using either traditional parabolic or more advanced electronic steering of array antennas.
Under certain conditions, other methods are required. For example, jammers are sometimes used to prevent detection by radar. Jammers often emit a powerful signal over the entire frequency range of the radar. In other cases, a moving target has such a slow motion that Doppler processing is unable to detect against stationary background clutter—such as a person or vehicle ...
