Deception jamming method based on micro‐Doppler effect for vehicle target

Abstract

Ground moving target is the main concern for ground surveillance radar. To protect the manoeuvring target from being detected by radar, some jamming technologies are utilised. In this study, a novel method of deception jamming for vehicle target against continuous wave ground surveillance radar is proposed. Traditional jamming method only considers the translation information. However, for vehicle target, micro-motion is obvious in some looking-angle and serves as an important property for target identification. Therefore, in this study, besides of the translational motion, the micro-Doppler (m-D) effect is also considered in the jamming modulation. The inclusion of the m-D signature improves the fidelity and effectiveness of the jamming result. Simulation results verify the effectiveness of the proposed algorithm.
