极化滤波器的性能比较

Performance Comparison of the Polarization Filter

基于极化滤波器的最优解,分析了最优极化滤波器的性能,并与固定极化、干扰抑制滤波器ISPF、信号匹配滤波器SMPF进行了比较。最优滤波器的性能比ISPF和SMPF平均要好1-3dB,比固定极化平均要好6-15 dB,最高可达30 dB以上。因此,最优极化滤波器的得益还是很可观的,这对研究最优极化理论的应用具有重要的理论指导意义和使用价值。

Based on the optimal polarization solutions for polarization filter, the performance of the optimal polarization filter is analyzed and compared with the fixed polarization, interference suppression polarization filter （ISPF）, and signal match polarization filter （SMPF）. On average, it is 1 -3 dB better than ISPF or SMPF, and 6 - 15 dB better than the fixed polarization. Thus, the gain of the optimal polarization filter is significant to the application of the optimal polarization filter.
