摘要
本文利用电磁信号的极化特性,研究了多散射源情况下利用变极化接收技术进行信号增强的问题,给出了分别以信号干扰噪声比和信号干扰功率差作为目标函数时接收天线的全局最优极化以及在极化轨道约束下的局部最优极化,并通过数值实例验证了文中的结论。
The polarization property of electromagnetic signals is utilized to investigate the prolem of sigal enhancement in the presence of multiple scatterers by means of changing the polarization of receiving antenna. The receiving antenna's global and local optimal polarizations with the constraint of polarization tracks are presented while adopting SINR (Signal-to-Interference-and-Noise-Ratio) and PDSI (Power-Difference-between-Signal-and-Interference) as the objective functions, respectively. The results are verified by a numerical example.
