ABSTRACT: In this paper we propose the polarimetric response in target characterization and SAR radar image classification. Polarimetric response is a graphical representation that is dependent on transmitted and received polarizations. The polarimetric response is given in a pair of two curves, one represents the copolarized response and the second represents the cross-polarized response. The ...

This paper introduces an approach to the classification and interpretation of SAR data using complementary polarimetric and interferometric information. Strictly polarimetric and polarimetric interferometric data are first analyzed and classified separately. An unsupervised polarimetric segmentation, based on multivariate Wishart statistics, is applied to one of the separate polarimetric datase...

Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) is a new trend of SAR remote sensing technology which combined polarized multichannel information and Interferometric information. It is of great significance for extracting DEM in some regions with low precision of DEM such as vegetation coverage area and building concentrated area. In this paper we describe our experiments with ...

Processing oversampled signals in range with a whitening transformation has been proposed as a means to reduce the variance of meteorological variable estimates on polarimetric Doppler weather radars. However, the original formulation to construct decorrelation transformations does not account for mismatches in the polarimetric channels, which results in abnormally biased polarimetric variable ...

Emission from an accretion disk around compact objects, such as neutron stars and black holes, is expected to be significantly polarized. The polarization can used put constraints on the geometrical physical parameters of sources – their radii, masses, spins well determine orbital parameters. radiation escaping innermost parts strongly affected by gravitational field object relativistic velocit...

This paper discusses an initial polarimetric calibration of ALOS PALSAR. ALOS was launched on January 24, 2006. PALSAR, which is one of ALOS three sensors, is the first spaceborne L−band polarimetric synthetic aperture radar. It is expected that PALSAR polarimetric data is used for many applications such as agriculture, forestry, ocean, natural disasters etc. Thus, polarimetric calibration is a...

in synthetic aperture radar (sar) imagery, ship-sea contrast can be significantly improved when the polarimetric information is used, compared with information from a single channel sar. the constant false alarm rate (cfar) detection algorithm based on the alpha-stable (as) distribution model is a descent method for ship detection in sea. the most important step in this method is the parameter ...

Remote sensing data, and radar data in particular, have become an essential tool for enviromental studies. Many airborne polarimetric sensors are currently operational, and many more will be available in the near future including spaceborne platforms. The signal-to-noise ratio of this kind of imagery is lower than that of optical information requiring, thus, a careful statistical modelling. Thi...

Radiative transfer is commonly modeled as the propagation of unpolarized radiation. More accurate approaches utilizing polarimetric quantities are usually only applied to sensors that purposefully discriminate polarimetric information. In this paper, we examine the effect on fidelity of utilizing polarimetric radiative transfer modeling for non-polarimetric sensors. We show that if the primary ...

We compare the measurement precision of a polarimetric camera to that of a simple intensity camera when imaging a partially polarized light-mark embedded in an intense and partially polarized background. We show that the gain in measurement precision while using a polarimetric camera is maximized when the noise fluctuations on the two polarimetric channels are significantly correlated. Further,...
