چکیده
In radar polarimetry, incoherent target decomposition techniques help extract scattering information from polarimetric synthetic aperture (SAR) data. This is achieved either by fitting appropriate models or optimizing the received wave intensity through diagonalization of coherency (or covariance) matrix. As such, depends on antenna configuration. Additionally, a descriptor that independent configuration might provide additional which missed individual elements implies existing characterization neglect this information. regard, we suitably utilize 2-D and 3-D Barakat degree polarization to obtain distinct for characterization. study, introduce new roll-invariant scattering-type parameters both full-polarimetric (FP) compact-polarimetric (CP) SAR These jointly use We these parameters, equivalent as Cloude ?

Compact Polarimetric Sar Product and Calibration Considerations for Target Analysis
Compact polarimetric (CP) data exploitation is currently of growing interest considering the new generation of such Synthetic Aperture Radar (SAR) systems. These systems offer target detection and classification capabilities comparable to those of polarimetric SARs (PolSAR) with less stringent requirements. A good example is the RADARSAT Constellation Mission (RCM). In this paper, some characte...

Classification of polarimetric SAR images has become a very important topic after the availability of Polarimetric SAR images through different sensors like SIR-C, ALOS-PALSAR etc. In this paper we studied effect of different decomposition techniques on the classification accuracy for polarimetric SAR data. We applied different target decomposition techniques (both coherent and incoherent) on A...

This paper deals with the problems of the negative powers and the overestimated volume scattering power of the Yamaguchi Decomposition, when applied to the urban areas. Three measures, namely the orientation angle compensation, a modified volume scattering model and two power constraints are appended in our algorithm. A RADARSAT-2 quad polarimetric image acquired over the Suzhou City in China i...
متن کاملA three-component scattering model for polarimetric SAR data
An approach has been developed that involves the fit of a combination of three simple scattering mechanisms to polarimetric SAR observations. The mechanisms are canopy scatter from a cloud of randomly oriented dipoles, evenor double-bounce scatter from a pair of orthogonal surfaces with different dielectric constants and Bragg scatter from a moderately rough surface. This composite scattering m...
متن کاملThree-Component Power Decomposition for Polarimetric SAR Data Based on Adaptive Volume Scatter Modeling
In this paper, the three-component power decomposition for polarimetric SAR (PolSAR) data with an adaptive volume scattering model is proposed. The volume scattering model is assumed to be reflection-symmetric but parameterized. For each image pixel, the decomposition first starts with determining the adaptive parameter based on matrix similarity metric. Then, a respective scattering power comp...
