Abstract :
A low-cost approach has been developed for positioning airborne radar-sounding data obtained over regions lacking evident visual features but having well-defined topography. By constraining radar profilometry to match a record of actual topography along the flight track, the method compensates for spatial sampling errors caused by local ground-speed variations. Profile alignment is accomplished using dynamic waveform matching and yields a transformation of the sounding data to geographic coordinates
