摘要
本文研究了极化测量过程中的信号增强问题,提出利用信号干扰功率差(PDSI)作为优化目标函数,以改善恶劣电磁环境中的信号接收质量。文中求解了以PDSI作为目标函数时的全局最优极化以及极化轨道约束下的局部最优极化,并给出最优极化对改善信号接收效果以及极化轨道对于改善信号接收效果有效度的定量描述。
In this paper,considering the problem of
signal enhancement in polarization measurement,the Power Difference between Signal and
Interference (PDSI) is adopted as the objective function to improve the reception of signal in the
complicate electromagnetic environments.The solutions of global optimal polarization and local
optimal polarizations on the polarization tracks of receiving antenna,while adopting PDSI as the
objective function,are presented.Also,the quantitative descriptions are given on optimal
polarization as well as the efficiencies of polarization tracks on signal enhancement.
