極化SAR相干斑抑制極化白化濾波器
Speckle reduction of polarimetric SAR-Polarimetric Whitening Filter
-
摘要: 相干斑抑制是合成孔徑雷達(SAR)圖像和極化SAR圖像后處理的首要問題。該文針對最優(yōu)的極化相干斑抑制濾波器極化白化濾波器(PWF)僅輸出一個強度圖像的缺陷,對 PWF進行了改進,得到了各個極化通道的強度圖像。

Abstract: Speckle reduction is the primary problem of SAR (Synthetic Aperture Radar) and polarimetric SAR imagery post-processing. Because the optimal polarimetric coherent speckle filtering-Polarimetric Whitening Filtering (PWF) has the drawback of only outputting a intensity image, this paper improves on it and get all polarimetric channel intensity images. -
