本文针对部分极化波情形,利用电磁波的Stokes矢量表示法研究了极化信号的优化接收问题;利用Lagrange乘子法,分别推导了以信号干扰功率差(PDSI)和信号干扰噪声比(SINR)作为优化目标函数时接收天线的全局最优极化;并通过数值实例验证了文中结论。
In this paper, for the partially polarized wave case, Stokes vector representation of electromagnetic wave is used to study the problem of optimal reception of polarized signals. The Lagrange multiplier method is used to derive the PDSI and SINR (Signal to Interference plus Noise Ratio) As the optimal objective function of the receiving antenna when the global optimal polarization; and verify the conclusion by numerical examples.
