极化轨道约束下的最优极化(二)

Optimal Polarization with the Constraint of Polarization Track（2）

本文针对相干极化测量过程中，在对接收天线极化进行圆环轨道约束的条件下，对于任意给定信号和干扰的极化方式，研究了圆环极化轨道上信号干扰噪声比（SINR）的局部最优化问题，并对Poincare极化球上大圆轨道约束与圆环轨道约束这两种情况下的SINR最优化问题进行了比较。对于测量过程中信号极化或干扰极化为已知的情况，本文提出了两种全局变极化策略，并研究了这两种策略对SINR最优化的影响以及二者在SINR优化过程中的搜索效率问题。

?In this paper． a polarimetric method with the constraint of circlet polarization trackon the receiving Polarization is Presented for coherent Polarized case． The local optimization ofSINR（signal－to－interference－and -noise－ratio） on the circlet track is investigated for the arbitrarypolarized signal and interference case． The comparison between the effects on SINR of the greatcircle track and the circlet track is given． Considering the fact that the golarization of signal orinterference is usually known In practice， two kinds of global polarlmetric strategies arepresented， and their effects on the optimization of SINR are studied．
