His professional expertise encompasses radar remote sensing, radar polarimetry, polarimetric scattering analysis, environmental change detection, polarimetric SAR image analysis for monitoring the planet earth. He and his group have developed “Four-component scattering power decomposition” for the utilization of polarimetric SAR image interpretation, which is one of the essential part of polari...

Ground-Based SAR system that obtains a high resolution 2D image on the ground is a new type of SAR system such as air-borne and space-borne SAR. The measured fully polarimetric SAR images with HH, HV, VH, and VV were focused using the Deramp-FFT (DF) algorithm in terms of their image formation principles. SAR polarimetry technique is concerned with control of the polarimetric properties of rada...

A statistical image model is proposed for segmenting polarimetric synthetic aperture radar (SAR) data into regions of homogeneous and similar polarimetric backscatter characteristics. A model for the conditional distribution of the polarimetric complex data is combined with a Markov random field representation for the distribution of the region labels to obtain the posterior distribution. Optim...

This paper makes the polarimetric and polarimetric interferometric synthetic aperture radar (PolInSAR) experiments with the highresolution X-band data acquired by Multi-mode airborne SAR system over an area around Linshui, south of China containing tropic vegetation and urban areas. Polarimetric analysis for typical tropic vegetations and man-made objects are presented, some polarimetric descri...

Radar Polarimetry and Polarimetric SAR Interferometry represent the current culmination in ‘Microwave Remote Sensing’ technology based on the Antennas, Propagation, Radar and Systems. The purpose and procedure of polarimetry and polarimetric interferometry are shown in Fig. 1. With polarimetric radar sensing, it is possible to carry out 1) detection of targets, 2) decomposition of scattering me...

In this paper, we will present the results of several case studies focusing on RADARSAT-2 InSAR monitoring of several different types of landslides and the uses of enhanced RADARSAT-2 polarimetric composites for surficial geological and terrain mapping in Canada. InSAR techniques are increasingly being used in slope stability assessment [1, 2 3]. Our research has shown that both differential In...

SAR Coherent Change Detection (CCD) is a technique that exploits the sensitivity of the transduced SAR image phase and speckle pattern to detect subtle scene disturbanes that may occur in the interval between a repeat pass imaging collection. Polarimetric SAR provides additional scene information that may be exploited to provide enhanced CCD products and yield improved detection performance. In...

Within the framework of the DRAGON project, a study of Polarimetric SAR Interferometry (PolInSAR) techniques for forests, and natural media in general, has been conducted. This paper focuses on two points. The first is a review of a general PolInSAR coherence model with respect to polarization diversity. The coherence constituents are identified and examined. The second part introduces two gene...

Polarimetric decomposition techniques and inversion algorithms are developed and applied on the OPAQUE data set acquired in spring 2007 to investigate their potential and limitations for soil moisture estimation. A three component model-based decomposition is used together with an eigenvalue decomposition in a combined approach to invert for soil moisture over bare and vegetated soils at L-band...

Synthetic Aperture Radar (SAR) polarimetry is an active and fruitful field of research in Earth observation. Polarimetry provides sensitivity to the soil moisture, as well as to the structural and geometric properties of the targets under observation, allowing a more accurate identification and classification than with non-polarimetric data. Moreover, the increasing number of spaceborne SAR sys...
