The Comparison of Speckle Reduction Methods for Polarimetric SAR Image Developed at ICA
极化SAR图像相干斑抑制的ICA方法与分析

The polarimetric SAR(synthetic aperture radar) image provides a very convenient approach for signal processing and acquisition of information from radar image. Based on statistical formulation of polarimetric SAR image, we present a new approach for speckle reduction using ICA (independent component analysis). In addition, we apply some ICA algorithms to real polarimetric SAR images and compare their performences. The comparison reveals characteristic differences between the studied ICA algorithms, complementing the results obtained earlier. The experimental results show that excellent performence can be achieved, the ENL is high and the image speckle noise is reduced effectively.
