This research effort examines the theory, application and results of side-looking airborne radar operation in hot clutter. Hot clutter is an electronic counter-measure used to degrade the performance of airborne radar. Hot clutter occurs by illuminating the ground with an airborne jammer at some velocity, azimuth, elevation, and range from the airborne radar. When the received RCS scattered hot clutter waveform is perfectly coherent with the radar waveform, the radar believes the returns created by the hot clutter jammer resulted from the transmitting radar. Hot clutter degrades radar performance at locations in azimuth and Doppler. The effect of hot clutter is examined for side-looking airborne radar using adaptive and non-adaptive processing. Factored Time Space and Joint Domain Localized adaptive filters are shown to improve radar performance 32 to 36 dB per element per pulse, respectively, over non-adaptive processing in the mainbeam jammer normalized Doppler location when the jammer is not in the radar look direction in azimuth.
