A Micro-Motion Feature Deception Jamming Method to ISAR

One of the main features of ISAR target recognition is the micro-motion feature. In order to jamming target recognition of ISAR, a micro-motion feature deception jamming method to ISAR based on digital image synthesizer is presented in this paper. In this method, the constant Doppler frequency of the scatterer in the template of false-target is replaced by the time-varying micro-Doppler frequency that produced by micro-motion scatterer, and the intercepted radar signals are modulated by the modified template of false-target in the slow time. The research results shows that this method can add the micro-motion information to the echoes of rigid body targets, and realize the micro-motion feature deception jamming to ISAR, Furthermore, the validity of the jamming method is justified by simulation experiment.
