| 摘 要： | 为进一步扩展可有效抑制短波电台干扰的极化滤波在非正交极化情况下的应用范围,提出了一种新的极化滤波方法,将目标和干扰信号的极化参数分别看做干扰子空间和信号子空间,构造斜投影算子形成斜投影极化滤波器,进而在时域和频域利用斜投影极化滤波器来消除干扰。理论分析和仿真结果表明该算法方便、有效,可对高频地波雷达系统中的电台干扰进行有效的抑制,是传统极化滤波器的推广。

| Abstract: | Polarization filtering technique has been developed as an efficient way to suppress radio interference in recent years.To further suppress the interference using polarization filtering technique when the target and the interference polarization parameter are non-orthogonal,a novel polarization filtering method is proposed,which is called the Oblique Projection Polarization Filter(OPPF).First,the polarization parameter subspaces of the target signal and interference are estimated in time and frequency domain... |
