Analysis of the Impact of Aircraft Maneuvers and Atmospheric Conditions on the Quality of Clutter Suppression in Space-Time Adaptive Processing

Space-time adaptive processing (STAP) of signal is a modern signal processing technique applied to radar systems. The STAP technique is used for the detection of objects moving on the ground through a airborne radar. STAP is designed to filter out echoes from sources of interference and preserve the signal coming from the object of interest. The article presents the problem of the influence of aircraft motion and, at the same time, the influence of atmospheric conditions on the quality of clutter filtering in the received echo signal using STAP. The paper presents a model of STAP signal processing for these phenomena, while simulations performed confirmed the existence of the analyzed problems.
