The limitations of basic active deception jamming model against SAR reconnaissance were analyzed detailed, and the necessary conditions of false target deployment for the model were derived. Some modifications and adjustment of the basic model were made, for which target-centric signal transmission schedule was proposed instead of jammer-centric schedule, time-varying repetition delay and time-varying Doppler parameters of false signal were made instead fixed parameters. The modified model extended false target’s displacement and improved the fidelity of false target. And some calculation examples and discussions were done in the end. |
