dc.descriptionAbstract: This report presents a technical evaluation of the likely performance of a Helicopter Lidar Bathymeter System (HLBS) that is being developed through an international agreement between the United States and Canada and is implemented through a joint Memorandum of Understanding under the US/Canadian Defense Development Sharing Program. Optech, Inc., is developing the HLBS, and the US Army Engineer Waterways Experiment Station is directing the overall development program. The program is two-phased. Phase I, the development of a conceptual design, was initiated in March 1988 and completed in March 1989. Phase II provides for the detailed design, fabrication, and field testing of an operational prototype system. This report presents the conceptual design of the HLBS, which is designed for use from a Bell 212 helicopter at altitudes ranging from 100 to 1,000 m. The system is intended for use in water depths from approximately 1.5 to 35 m. Horizontal control will be provided either by microwave or the NAVSTAR Global Positioning System. System components include an Nd:YAG laser transmitter/receiver with scanning device; an onboard system to acquire, initially process, and store all sensed data such as time, depth, and position; a system to provide the pilot with real-time navigation guidance; an aircraft attitude recorder for removing aircraft pitch and roll; a horizontal positioning system; and a status panel so the onboard operator can monitor system parameters and confirm that valid data are being collected. A ground-based system which postprocesses the collected data will produce as the final system product a fully corrected and quality~hecked file of position and water depth referenced to standard survey control.
