The 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...

Ocean Feature Monitoring with Wide Swath Synthetic Aperture Radar

y providing better spatial coverage, wide swath synthetic aperture radar (SAR) can offer a more complete picture of various mesoscale ocean features. With better temporal coverage, SAR also supplies crucial information for the tracking and monitoring of these features using, for instance, the technique of two-dimensional wavelet analysis. Examples presented in this article of fronts in the Gulf...

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...

Measurements of Directional Wave Spectra by the Shuttle Synthetic Aperture Radar

During October 1984, measurements of directional ocean wave spectra in high sea states were made off the coast of Chile, near Tierra del Fuego, by a synthetic aperture radar aboard the space shuttle Challenger. Simultaneously, independent measurements of ocean wave spectra were made by a complement of airborne instruments. The results indicate that a low-altitude orbiting synthetic aperture rad...
