Change detection in polarimetric synthetic aperture radar data [PDF]

, 2019
Based on an omnibus likelihood ratio test statistic for the equality of several variance-covariance matrices following the complex Wishart distribution and a factorization of this test statistic with associated p-values, change analysis in a time sequence of multilook polarimetric SAR data in the covariance matrix representation is carried out.

Calibration Issue in SMART Synthetic Aperture Radar Based on Scan-On-Receive [PDF]

, 2009
A new spaceborne Synthetic Aperture Radar (SAR) system based on SCan-On-REceive (SCORE) algorithm has been recently proposed in order to overcome the trade-off between spatial resolution and swath wide of current SAR systems. The compound architecture of

Precipitation Induced Signatures in SAR Images [PDF]

, 2009
Active microwave SAR imaging of the Earth’s surface is commonly considered to be of all weather capability. However, as the operating frequencies of SAR-systems are increasing, visible image distortions due to heavy precipitation in SAR-images are ...

Polarimetric Synthetic Aperture Radar : Theory and Application

Polarimetric Synthetic Aperture Radar : Theory and Application
[ABSTRACT]Scattering power decomposition theory and some images of fully polarimetric synthetic aperture radar data are presented for disaster monitoring. Utilization of fully polarimetric data can derive full color images with red-green-blue color coding, red for the double-bounce power, green for the volume scattering power, and blue for the surface ...

Trend on Polarimetric Synthetic Aperture Radar Techniques

Trend on Polarimetric Synthetic Aperture Radar Techniques
[ABSTRACT]The outstanding performance capabilities of the three Satellite POLSAR sensors are well established; and in this exposition the exploitation of the fully polarimetric ALOS-PAL=PPL=SAR mode is demonstrated by implementing the NIIGATA-UNIVERSITY four-scatterer SAR image decomposition with coherency-matrix rotation proving the superior imaging ...
