Reconsideration of Ambiguities in Quad-Pol SAR
Merging the complex signals available from both cross-polarized (cross-pol) channels of a quad-polarimetric (quad-pol) synthetic aperture radar (SAR) may lead not only to a 3-dB gain in the signal-to-noise ratio (SNR), but also to a remarkable improvement in the azimuth and range ambiguity-to-signal ratios (AASR, RASR) of cross-pol data, especially if azimuth phase coding is employed. Staggered...
متن کاملClassification Comparisons between Compact Polarimetric and Quad-pol Sar Imagery
Recent interest in dual-pol SAR systems has lead to a novel approach, the so-called compact polarimetric imaging mode (CP) which attempts to reconstruct fully polarimetric information based on a few simple assumptions. In this work, the CP image is simulated from the full quad-pol (QP) image. We present here the initial comparison of polarimetric information content between QP and CP imaging mo...
متن کاملUsing Quad-pol and Single-pol Radarsat-2 Data for Monitoring Alpine and Outlet Antarctic Glaciers
This paper presents some applications of the Maximum Likelihood (ML) texture tracking on displacement estimation of some alpine and antarctic glaciers surfaces. This method is adapted to the statistical characteristic of the new High Resolution (HR) Polarimetric SAR (PolSAR) data. The ML texture tracking method is firstly reminded and a statistical model of HR PolSAR data is explained. The main...
متن کاملALOS PALSAR Quad-Pol Data for Soil Moisture Mapping
ALOS PALSAR quadpol data acquired over two test sites of India were processed and analysed for soil moisture mapping and classification. Polsarpro software and some programs developed by us were used for the processing of the data. Data were classified using H/A/Alpha Wishart technique. PauliRGB and classified images give a lot of details about various land features. For soil moisture mapping, ...
متن کاملFeature extraction of dual-pol SAR imagery for sea ice image segmentation
Dual-polarization synthetic aperture radar (SAR) image data, such as that available from RADARSAT-2, provides additional information for discriminating sea ice types compared to single-polarization data. A thorough investigation of published feature extraction and fusion techniques for making optimal use of this additional information for unsupervised sea ice image segmentation has been perform...
