A recently developed technique, polarimetric radar interferometry, is applied to tackle the problem of the detection of buried objects embedded in surface clutter. An experiment with a fully polarimetric radar in an anechoic chamber has been carried

This paper presents a study of the interferometric coherence aimed to the understanding of the main sources of phase error of an operative wide band system. This objective is accomplished by finding a theoretical expression of coherence based on a su

It is generally accepted that the best way to retrieve sea surface salinity (SSS) is by means of L-band radiometry (1400-1427 MHz). However, in addition to the polarization and the incidence angle, the SSS and the sea surface temperature (SST), the s

A coherence optimization method, which makes use of polarimetry to enhance the quality of the interferograms, has been experimentally tested under laboratory conditions in an anechoic chamber. The experiments have proved the remarkable contribution t

Applying polarimetric interferometric methods to invert vegetation parameters from SAR-data

Autor: X. Fabregas, A. Ulbricht, L. Sagues

Publikováno v: IGARSS 2001. Scanning the Present and Resolving the Future. Proceedings. IEEE 2001 International Geoscience and Remote Sensing Symposium (Cat. No.01CH37217).

In this paper the use of polarimetric interferometric SAR data for extracting vegetation parameters is studied. For this purpose an inversion algorithm is performed with indoor polarimetric interferometric SAR measurements by applying a simplified sc
