Low-Backscatter Ocean Features in Synthetic Aperture Radar Imagery
any ocean surface signatures in synthetic aperture radar (SAR) imagery are characterized by relatively low normalized radar cross section values. Distinguishing among these signatures objectively can be very difficult, especially with only the singleband and single-polarization SAR imagery available from the European Remote Sensing satellites and the Canadian Radarsat-1. Nevertheless, distincti...
متن کاملBuilding Height Retrieval from Radiometric Parameters on Sar Images
Urban structure detection, in terms of both geometric and electromagnetic features, from a single Synthetic Aperture Radar (SAR) image is, nowadays, an interesting still open challenge. Within this framework a new deterministic approach for the extraction of the height of an isolated building on a rough terrain is presented. The approach is based on a sound electromagnetic model which fully rep...
متن کاملA comparison of spatial sampling techniques enabling first principles modeling of a synthetic aperture RADAR imaging platform
Simulation of synthetic aperture radar (SAR) imagery may be approached in many different ways. One method treats a scene as a radar cross section (RCS) map and simply evaluates the radar equation, convolved with a system impulse response to generate simulated SAR imagery. Another approach treats a scene as a series of primitive geometric shapes, for which a closed form solution for the RCS exis...
متن کاملA Robust SAR NLFM Waveform Selection Based on the Total Quality Assessment Techniques
Design, simulation and optimal selection of cosine-linear frequency modulation waveform (CNLFM) based on correlated ambiguity function (AF) method for the purpose of Synthetic Aperture Radar (SAR) is done in this article. The selected optimum CNLFM waveform in contribution with other waveforms are applied directly into a SAR image formation algorithm (IFA) and their quality effects performance ...
متن کاملComputation of Wind Vectors over the Ocean Using Spaceborne Synthetic Aperture Radar
he high resolution and large coverage of satellite synthetic aperture radar (SAR) offer a unique opportunity to derive mesoscale wind fields over the ocean surface and to investigate their spatial variation. For this purpose, different algorithms were developed and tested using SAR images from two European Remote Sensing satellites. In this article, the methods for deriving wind fields from SAR...
