The Coast Guard CG Research and Development Center RDC, funded by the Naval Submarine Medical Research Laboratory NSMRL, evaluated the detectability of the SeeRescue S-R streamer distress signal device in scenarios relevant to Navy search and rescue operations using data collected during two sea test exercises with the following technical objectives. 1. Determine lateral range curve LRC functions and sweep width W values for the visual acumen of Naval P-3 aircrews searching without visual aids i.e., eyes only during the day. The crews searched for persons in the water PIWs with an S-R streamer, submarine escape and immersion equipment SEIE life rafts with an S-R streamer, and SEIE rafts without the S-R streamer. 2. Determine cumulative detection probability CDP curves for two search periodsmethods during the day with no visual aids and at night wearing night vision goggles. The search objects were PIWs and SEIE rafts with S-R streamers and SEIE rafts without the S-R streamer. 3. Perform a statistical comparison of the detectability of the PIW and SEIE search objects when equipped with vs. without an S-R streamer. Data collected from the two sea tests were analyzed, and the findings of these analyses are presented.
