Optimum Reception of Radar Polarization Signal in Complex Electromagnetism Environment

利用极化轨道的概念实现了变极化自由度的降维过程,将极化轨道上的极化滤波推广到了多散射源的情况,并在极化轨道约束下研究了信号干扰功率差的优化问题,通过仿真对利用局部最优化改善信号接收的效果及性能进行分析,对我军在复杂电磁环境下的作战和训练有较高的参考价值。

Using the conception of polarization orbit, this paper realizes the process of reducing the dimensions of variable polarization freedom, extends the polarization filtering in polarization orbit to the state of multi-scatter-source, and researches the optimization of power difference between signal and interference under the restriction of polarization orbit, analyzes the improved reception effect and performance of signal by using the part optimization through simulation, which has good reference to our battling and training in complex electromagnetic environment.
