Application of STAP For Detection of Target In The Presence of Ground Clutter

Abstract

For Airborne radars it is necessary to suppress the levels of the interferers well below the weak desired signal. The problem is complicated due to the motion of the radar platform as the ground clutter received by airbornne radar is spread out in range, angle and over Doppler. Space-Time adaptive processing (STAP) is a technique, which helps to detect small signal of interest in such a noisy environment. This paper considers a generic clutter model. The simulations clearly bring out the 2-D nature of ground clutter and give an insight into the noisy environment in which the target is detected.
