N2 - To protect the structural feature and polarimetrie property in the speckle reduction of polarimetrie synthetic aperture radar (PolSAR) images, an improved speckle filter is developed based on a novel structural judgment and an improved four-components polarimetric decomposition (IFCPD) proposed from the Pauli decomposition and the Yamaguchi decomposition. The novel structural judgment based on the wavelet transform and a pixel sort technique divides PolSAR image pixels into bright targets, dark targets, and the background, which enables the improved speckle filter to protect the structural feature with a higher efficiency and a better result comparing with the existing speckle filter methods. The IFCPD enables the improved speckle filter to protect the polarimetric property by dividing the dark targets and the background into four scattering classes, respectively. The IFCPD inherits the merits of the Pauli decomposition and the Yamaguchi decomposition, and can be used in the single look complex (SLC) data without multilook processing, which makes the decomposition results get rid of the influence of adjacent pixels. The validity of proposed method has been demonstrated by the experimental results of the GF-3 data.
