A new deceptive jamming method for SAR based on false moving targets

In SAR/GMTI, static jamming such as noise and deceptive scene will be eliminated as clutter, and will make no sense. In this paper, a deceptive jamming method for SAR is lucubrated to protect military moving targets. For false moving targets (FMT) consisting of many scattering centers, we propose an improved way to generate false signals. Through separating the response function of false signals into range-related and azimuth-related parts, the new method can reduce the algorithm complexity effectively. Moreover, the factors which will affect the jamming efficiency are analyzed. Simulation results show that the new method is effective to SAR/GMTI and the conclusions are valid.
