Abstract: Considering the problem that the relocation of false targets under single jammer is uncontrollable after three antennas SAR-GMTI processing， which makes them always return to the jammer’s position， a deception jamming method is proposed in this paper， which is based on amplitude-frequency cooperative modulation of multiple jammers. First， the cooperative jamming model of multiple jammers is established， which is based on noise multiplication. Then， according to the analytical expression of SAR-GMTI output， the principle of cooperative deception is analyzed theoretically and the amplitude-frequency cooperation condition of multiple jammers is deduced. Afterwards， the performance of the proposed jamming method is analyzed in detail. Simulation results demonstrate that the proposed cooperative jamming method of multiple jammers can effectively control the relocation of false targets. Compared with convolution modulation， the proposed method can greatly reduce jamming modulation time， which provides some reference values for engineering applications.
