Velocity deception jamming involves actively and coherently modulating a false Doppler shift onto a pulse intercepted by a digital radio frequency memory to mimic the moving characteristics of a physical target, leading to the loss of the target's true velocity tracking. This article presents a study on the interpulse polarization modulation scheme, emphasizing the minimization of weighted integral sidelobe level of the target echo and integral cross-correlation energy of the jamming within specific stopbands to optimize the receive filter, waveform, and polarization sequences, which achieves a tradeoff between the increased design freedom of waveforms and the complexity of polarimetric radars. Experimental results based on full-polarization data of a T-72 tank demonstrate the effectiveness of the introduced optimization of pulse polarization in significantly reducing jamming levels. Furthermore, the validation underscores the importance of considering the modulation effect on a pulse from an extended target in the signal-to-interference plus noise ratio expression.
