摘　　要：当2路极化信号的相位变化、幅度变化、信噪比变化时,文中给出了最佳信噪比合成条件以及合成后所能达到的极限性能的推导,同时给出了工程实现的方法和详细计算仿真结果。该项研究对工程实践具有重要的指导意义。The optimal signal-noise ratio(SNR) synthesis conditions and its limit performance for double-channel polarized signals with time-varying phase,fluctuating amplitude and variant signal-noise ratios have been deduced.Besides,the implementation methods related to this method were proposed and simulation results were shown in detail in this paper.This study has certain reference value for practical operation of receiving system.
