| Abstract: | Firstly the polarimetric covariance matrix and the statistical properties of the target which has been interferenced is derived, the mathematical model for optimal polarization detec-tor under interference conditions is established, then to take surface ships and armored vehicles for example to analyze the effect of different interference power and jammer polarization configu-rations on polarimetric radar target detection capabilities, revealing the optimal jamming power demand which make use of repressive jamming to reduce polarimetric radar target detection per-formance. |
