Polarimetric Segmentation of Synthetic Aperture Radar Imagery
This paper considers the problem of clutter segmentation in fully polarimetric, high resolution, synthetic aperture radar (SAR) imagery. The goal of segmentation is to partition an image into regions of homogeneous terrain types (grass regions, tree regions, roads, etc.). Three approaches to segmentation are examined: (1) the optimal polarimetric classifier, (2) the optimal normalized polarimet...
متن کاملThe Object Detection Efficiency in Synthetic Aperture Radar Systems
The main purpose of this paper is to develop the method of characteristic functions for calculating the detection characteristics in the case of the object surrounded by rough surfaces. This method is to be implemented in synthetic aperture radar (SAR) systems using optimal resolution algorithms. By applying the specified technique, the expressions have been obtained for the false alarm and cor...
متن کاملAutomatic Target Detection and Recognition Using Synthetic Aperture Radar Imagery
Importance of Image Exploitation Defence forces rely upon a variety of sensor information to locate and track oppositional forces; the surveillance problem becomes particularly difficult over large land areas with sparse population centres and over the great expanse of the seas. The modern warfighter is dependent upon several types of image data to aid in the surveillance task including optical...
متن کاملLow-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 کاملFeature matching and target recognition in synthetic aperture radar imagery
An approach for target matching in Synthetic aperture radar (SAR) imagery is presented. The method is feature based where feature points in a target candidate are matched against those from an exemplar database. Matching is formulated as a non-linear optimization problem that encourages matches while minimizing the distance between the matched features. The formulation allows for missing, spuri...
