| Abstract: | Aiming at calculation problem of deception jamming against SAR,the evaluation and calculation model of SAR active deception jamming based on Point Spread Function are proposed.Firstly,the energy analytical formula for impulse response of the system and its error model are derived.Secondly,the equivalent calculation model is given.At last,the performance is analyzed.Simulation shows that the model has validity and accuracy. |
