Abstract:

This report assesses the search performance of Coast Guard units employing both visual and electronic sensors in detecting small boats 16 to 21 feet and life rafts. A comparison is also made between real-time search performance and post-search videotape analysis for a prototype Coast Guard forward-looking infrared FLIR system. Based upon data collected during eight experiments, lateral range curves and sweep width estimates are developed for combined surface vessel radar SVRvisual and side-looking airborne radar SLARvisual searches. This analysis demonstrates that, in many situations, combined sensor search is significantly more effective than single-sensor search. The FLIR analysis demonstrated that human factors can degrade the present FLIR systems detection capability. Combined sensor search guidance is recommended and suggestions for further data collection and analysis are made.
