Resumo
Radar is an active remote sensing system because it provides its own source of energy. Toe system illuminates the terrain with electromagnetic energy, and detects the energy returning from the terrain. Toe continuous-strip mapping capability of side-looking airbone radar (SIAR) was developed in the 1950s to acquire reconnaissance images without the necessity offlying over certain regions. Toe synthetic-aperture radar (SAR) employs the Doppler principie and special data processing techniques to synthesize the azimuth resolution of a very narrow beam. Toe main applications of radar technique are: Agriculture: information concerning cropping and crop production. I:orestry: forest and environmental policy. Geology: structuraL lithologicaL geomorphological and soil maps. Ice and snow: mapping the extent the ice. Oceanography: scientific study ofthe oceans. Geological risks: catastrophes, fires.
