Remote sensing of radar polarimetry has great potential to determine the extent and properties of snow cover. Availability of spaceborne sensor dual polarimetric C-band data of ENVISAT-ASAR can enhance the accuracy in measurement of snow physical parameters as compared to single fixed polarization data measurement. This study shows that the capability of C-band SAR data for estimating dry snow density...
Polarimetric SAR provides a substantial source of information over conventional imaging radars. Fully polarimetric PALSAR data has been used for land cover classification. Co and Cross Polarization signatures for different classes are obtained in linear (h,v) and circular (l.r) basis. Different combinations from both basis have been extracted for the (principal component analysis) PCA. Supervised...
Snow cover is the important parameter for hydrological modeling and climate change modeling. Land use/cover classification is one of the most important applications of polarimetric synthetic aperture radar (POLSAR) sensing. Hence, the application of radar polarimetry is one of the best remote sensing techniques to classify snow cover terrain. In this paper, PALSAR data have been analyzed of snow cover...
Land cover monitoring is one of the most potential applications of Polarimetric Synthetic Aperture Radar (POLSAR) sensing and so is Repeat-Pass Polarimetric-Interferometric SAR (RP-DIFF-POL-INSAR) stress-change assessment by air/high-altitude/space-borne SAR sensor deployment. Provided fully polarimetric SAR information can be made available, a plethora of novel POLSAR matrix decomposition methods...
The main aim of this paper is to check the microwave response on soil texture in specular direction. For this purpose, an indigenous bistatic scatterometer has been assembled at C-band which has facility to change incidence angle from 25deg to 70deg and can take observation in both like polarization (i.e., HH and VV-polarization). Four fields has been prepared with different soil texture (i.e., sand,...
Worldwide, medium- to short-term earthquake prediction is becoming ever more essential for safeguarding man due to an un-abating population increase, but hitherto there have been no verifiable methods of reliable earthquake prediction developed - except for a few isolated examples of earthquake prediction in China and in Greece. This dilemma is a result of previous and still current approaches to...
SIR-C quad-pol MLC data and ALOS PALSAR quad-pol and dual pol SLC data over Indian sites have been processed using PolSARpro software for classification of various land features. The land features include ocean, clear water, settlements, agriculture fields, arid lands, grown and young forest, hilly terrain, mangrove forest, etc. The test sites used are SIR-C L-band and C-band Kolkata city and its...
The development of radar polarimetry and radar interferometry is advancing rapidly, and these novel radar technologies are revamping "synthetic aperture radar imaging" decisively. In this exposition the successive advancements are sketched; beginning with the fundamental formulations and high-lighting the salient points of these diverse remote sensing techniques. Whereas with radar polarimetry...
