Analysis of deception jamming effect in range imaging

The linear frequency modulation signal and the pulse-compressed technique have been widely used in model radar. In order to jam effectively the radar, the DRFM technique and the ways of time-shift, weighing and frequency-shift were adopted to produce immobile false targets, moving false targets, and false targets with a few moving parts, respectively. The simulation of jamming signals and echo signals via the signal processing with a certain ratio of energy and deception jamming in range and velocity were analyzed. As the jamming energy grows greater, the parameters of synthetic targets gets much closer to those of jamming targets, so the velocities and sites of the real targets are concealed, and a better jamming effect is obtained.
