Aircraft sometime crash in forested areas without leaving an easily detectable entry point or other indication that a crash has occurred. The wreckage can be completely obscured by overhead vegetation, which makes locating efforts, by air and ground search teams nearly impossible. In addition, there are many times, for many reasons, that emergency beacons fail to operate after a crash has occurred. For these cases, NASA has been experimenting with airborne synthetic aperture radar to provide a search tool to help focus the visual searches that are initiated after an aircraft is reported missing. This paper reviews a proposed operational scenario and the elements of a prototype airborne system that could be brought into use for finding crashed aircraft obscured from view.
