Modeling of synthetic aperture radar (SAR) images has been an important topic of research since the inception of SAR satellites. Many theoretical and empirical models have been presented in literature to accurately model the amplitude SAR images. The method of parameters estimation of the probability density function (PDF) for selected models is another(More)
—The advent of submeter-resolution synthetic aperture radar (SAR) images from satellites such as TerraSAR-X has given a new dimension to SAR image understanding. Even though emphasis is always on discovering automatic means of target characterization , visual exploration of targets and objects is the first step in many applications. While considering the(More)
In this paper we compare Gauss-Markov Random Field (GMRF) and 4-D Representation based Time Frequency Analysis (TFA) methods for the analysis of targets in complex valued high-resolution SAR data. This work is based on the work carried out in [1], [2] & [3], [4] and it is an extension of the work presented by authors in [5]. In [1], [2] a parametric(More)
Many users of Earth observation SAR images are only interested in individually selected application tasks. Thus, instead of applying universal data analysis tools, SAR users often aim at interactively controlled feature determination based on object size, object motion, double bouncing, or occultation. In contrast to these typically geometry-driven(More)
