Imaging radar

From Biocrawler, the free encyclopedia.

Traditional radar sends directional pulses of electromagnetic energy and detects the presence, position and motion of an object (such as an airplane) by analyzing the portion of the energy reflected from the object back to the radar station. Imaging radar attempts to form a picture of the object as well. Several techniques have evolved to do this. Generally they take advantage of Doppler shift cause by rotation or other motion of the object and by the changing view of the object caused by relative motion of the radar and the object, e.g. a radar-equipped plane flying over the earth. Imaging radar has been used to map the Earth and other planets and to categorize targets for military systems.
