An Investigation of Range-velocity Deception Jamming Modeling

This paper explores the modeling method of rangevelocity deception jamming, which can deceive the victim radar on range and velocity information simultaneously.By analysis of the producing mechanism, maneuvering strategies and pulling rules of this jamming, the basic mathematical models are established by stages, as well as target echo and jamming models for pulse compression radar.Then based on the radar with LFM and Barker phase-coded signal, the specified models of the jamming are deduced.Simulation results show the received signal waveform when the target echo is presented in range-gate-pull-in and velocity-gatepull-in jamming (RGPI-VGPI) and range-gate-pull-off and velocitygate-pull-off jamming (RGPO-VGPO) environment.This will provide theoretical basis to Electronic countermeasures (ECM) and Electronic counter-countermeasures (ECCM) concerning rangevelocity deception jamming.
