Abstract
- Small unmanned aircraft or other aircraft that operate at short range are likely to need to operate at steep look-down angles. Imaging at high grazing angle causes range-layover which affects synthetic aperture radar (SAR) images in the down-range direction, but not in cross-range. By making a number of images at different look angles relative to the target, the 3-D position of individual scatterers on the target can be calculated, as long as they remain visible over an appreciable angular extent. The range-layover to height mapping algorithm is presented here for forming 3-D images from high grazing angle SAR data. This algorithm only requires data collected from a single antenna and a single pass of the target to form a 3-D image. [ABSTRACT FROM AUTHOR]
