Paper Abstract

The U.S. Navy is presently constructing and flight testing the Airborne Bathymetric Survey System which contains as one of its sensors a lidar system. Automated post-flight waveform processing software has been developed around several sets of heuristic rules to reliably extract accurate depths while exhibiting a low false alarm rate. In 1987, flight tests were conducted in the Key West, Florida area to develop hardware and to provide data for exercising the processing procedures. The performance of the waveform processor, including noise immunity, target discrimination, and limiting cases, is presented. Interesting environmental effects on the surface returns, volume backscatter, and bottom returns are detailed. Work in progress, including comparisons of different pulse location algorithms, is noted.
