Paper Abstract

For the problem of finding downed aircraft in forested areas, the NASA Search and Rescue Project has developed a system based on using fully polarimetric L-Band and P-Band synthetic aperture radar (SAR). Because of the resolution of the sensor and the size of the target, single-look imagery must be used. The problem of focusing the SAR imagery is a difficult one, especially at P-Band. An approach has been implemented with considerable success, based on a variant of the phase gradient autofocus algorithm, which provides the higher-order-than- quadratic phase correction needed.
