SAR Imagery: Its Application to Oceanography

摘要

Synthetic Aperture Radar (SAR) is a side-looking imaging radar system operating from a moving platform. It presents an opportunity to obtain two-dimensional spatial information about the earth with high resolution under all weather conditions. After the launch of Seasat (the first SAR satellite made by USA) in 1978, SAR imagery is getting widely used in almost every category of earth science (oceanography, atmosphere, forestry, hydrology, glacier and ice, soil moisture, land use etc.). This paper demonstrates the applications of ERS-1/2 and Radarsat SAR imagery to varies fields of oceanography such as ocean surface wind fields, surface waves, internal solitons, tropical rain cells, eddies and fronts etc..
