Airborne Stereo Multispectral scanner (ASMSS) for Bathymetric Survey and Reconnaissance.

摘要

The Airborne Stereo Multispectral Scanner (ASMSS) mission and design scenario are described. The obstacles to successful development of the scanner system are detailed. Results of simulation trials to determine errors relevant to system design considerations are provided. Finally, a relatively simple competing design scenario is presented. The rapid surveying of water depths, elevations, and surface material cover in coastal areas remains a significant concern for the Navy and the Defense Mapping Agency (DMA). Currently, the problem is being addressed by the development of the Airborne Bathymetric Survey (ABS). The ABS is composed o f a laser sounder and a multispectral scanner, which operates at Thematic Mapper wavelengths. The laser sounder provides control points in the MSS image so that, with adaptive filter techniques, bathymetry may be extracted from MSS imagery. However, the use of a laser imposes power and weight restrictions on the airborne platform, as well as significant repair and maintenance problems. Reprints. (RRH)
