Micro-Doppler Deception Jamming for Tracked Vehicles

As tracked vehicles play significant roles in a battlefield, effective jamming measures is necessary to protect them from being perceived by hostile radar. Moving tracked vehicles exhibit strong Doppler and micro-Doppler signatures. Therefore, the jamming signal should include micro-Doppler modulation generated by metallic caterpillars for successful deception jamming. Based on detailed analysis of kinetic characteristics of tracked vehicles, this paper proposes a new deception jamming method for tracked vehicles against continuous-wave ground surveillance radar. To obtain precise deception jamming effect, this method achieves both translational modulation for rigid parts and micro-Doppler modulation for the caterpillars. Finally, simulation results have proven the effectiveness of the proposed method.
