Research on Composite Deception Interference Recognition and Suppression Technology Based on Multi-Dimensional Features

Abstract

Aiming at the complex form of complex deception jamming signal and the difficulty of recognition, a hybrid deception jamming recognition and suppression algorithm based on multi-dimensional feature extraction is proposed. Firstly, using the uniqueness of the spatial position coordinates of the false target in the radar network, the spatial characteristics of the composite interference are extracted, and the distance false target, the angular vacation target and the distance-angle compound deception jamming are identified and suppressed. Then, the motion feature is further introduced. Using the difference characteristics of radial velocity estimation and Doppler velocity measurement, the distance-velocity deception jamming, angle-speed deception jamming and distance-angle-speed deception jamming are identified and suppressed. Finally, by extracting multiple times of compound deception jamming Features to further improve the effectiveness of the identification of compound fraud interference. The simulation results show that the algorithm can effectively identify and suppress the composite deception jamming.
