Improved Target Detection in Polarimetric Sar Images by Use of Mellin Kind Statistics
نویسندگان
چکیده
We present a modified version of the polarimetric whitening filter (PWF) for target detection in single-look complex images captured by polarimetric synthetic aperture radar (PolSAR). The modified version enables the derivation of the sampling distribution of the PWF under several product model distributions for the polarimetric scattering vector. Specificly, a constant false alarm rate (CFAR) detector is obtained under the K-distribution and the Gdistribution. The PWF sampling distribution as well as efficient estimators for shape parameters characterising the radar texture are derived by use of newly proposed Mellin kind statistics for single-look complex PolSAR data.

The monitoring of maritime areas with remote sensing is essential for security reasons and also for the conservation of environment. The synthetic aperture radar (SAR) can play an important role in this matter by considering the possibility of acquiring high-resolution images at nighttime and under cloud cover. Recently, the new approaches based on the sub-look analysis for preserving the infor...
متن کامل[hal-00350055, v1] Fisher distribution for texture modeling of polarimetric sar data
The multi-look polarimetric SAR covariance matrix is generally modeled by a complex Wishart distribution. For textured areas, the product model is used and the texture component is modeled by a Gamma distribution. In many cases, the assumption of Gamma distributed texture is not appropriate. The Fisher distribution does not have this limitation and can represent a large set of texture distribut...

The last few decades witnessed high urban growth rates in many countries. Urban growth can be mapped and measured by using remote sensing data and techniques along with several statistical measures. The purpose of this research is to detect the urban change that is used for urban planning. Change detection using remote sensing images can be classified into three methods: algebra-based, transfor...
متن کاملApplication of Mellin-Kind Statistics to Polarimetric ${\cal G}$ Distribution for SAR Data
The K distribution can be arguably regarded as one of most successful and widely used models for radar data. However, in the last two decades we have seen tremendous growth in even more accurate modeling of radar statistics. In this regard, the relatively recent G distribution filled some deficiencies left unaccounted by the K model. The G model actually resulted as a special case of a more gen...

Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...
