本文针对极化测量过程中干扰和噪声对接收效果的影响，提出一种极化轨道约束下的变极化接收方法，以改卷接收系统的SINR（信号干扰噪声比）。在极化轨道约束下的SINR最大化问题是一个寻求局部最优的问题，本文在任意的信号与干扰极化条件下，解决了任意给定的极化轨道上SINR的最大化问题，并对极化轨迈上最优极化与其他两种最优极化得到的SINR进行了比较。
In this paper, aiming at the influence of interference and noise on the receiving effect during the polarization measurement, a polarization-dependent receiving method is proposed to change the SINR (Signal to Interference and Noise Ratio) of the receiving system. The SINR maximization problem under the polarization orbital constraint is a problem that seeks local optimization. In this paper, the problem of maximizing SINR on any given polarization orbit is solved under arbitrary signal and interference polarization conditions. Polarization trajectories into the optimal polarization and the other two optimal polarization obtained SINR were compared.
