| 摘 要： | 针对高分辨极化雷达检测中极化滤波器的选择问题,提出了在检测中根据干扰信号极化度的估计值大小,选择干扰抑制极化滤波器对回波进行极化滤波,或者选择信干比较大极化通道信号的检测方法。仿真实验结果表明,在干扰信号极化度未知且变化时,该方法可以保证检测器输入端具有较高的信干比,从而有利于提高检测性能。 |

| Abstract: | The selection of polarization filter for high-resolution polarimetric radar detection is investigated, and a detection method is proposed which uses interference suppression polarization filter (ISPF) or selects the polarization channel with higher signal-to-interference ratio (SIR) for detection according to the estimate of the degree of polarization (DoP) of the interference. Simulation results indicate that in the case of interference with unknown DoP, this method can maintain a high SIR of the detector input, which is in favor of detection. |
