极化轨道约束下的最优极化(一)

Optimal Polarization with the Constraint on Polarization Track(1)

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, a polarimetric method with the constraint of polarization track is presented to improve SINR (Signal-to-Interference-and-Noise-Ratio), while considering the effect of interference and thermal noise on the reception of antenna. It is a local optimization problem to maximize SINR on the constraint of polarization track. The solution is derived ofr the arbitrary polarized signal and interference case when the plarization track is given. A comparison between the SINR under optimal receiving plarization on the track and the other two optimal polarizations is presented.
