Suppression of terrain-scattered jamming in pulse compression radar

This letter presents research results on a new method for the suppression of terrain-scattered clutter due to jamming of the radar footprint. The method applies temporal adaptive filtering to the received radar signal that removes the correlated clutter component. This approach relies on the transmitted radar signal having coded phases, such as a discretized chirp or polyphase waveform. Because of the prior knowledge of coded phase of the transmitted waveform, it is not necessary to have an auxiliary record of the jamming signal to achieve clutter suppression.<>
