Abstract: A low cost Swimmer Detection Sonar Network (SDSN) is now being developed under an ONR Phase 2 SBIR and as a joint project between the USA and Singapore. The SDSN is a network of inexpensive sonar nodes where narrow sonar beams are formed using air-backed parabolic reflectors. The feasibility of the system has been proven through trials conducted in Singapore harbor and full development is well underway. Currently each parabolic reflector has a single transducer at the focal point and is used for both transmission and reception. There is one parabolic reflector for each beam, with up to 10 beams per node. A substantially less complex, cheaper, and smaller node might be realized using a single wide-beam transmitter and a multi-beam air-backed spherical reflector receiver. Initial modeling shows promise. The Phase 1 effort would include more thorough modeling, testing of a multi-beam air-backed spherical reflector receiver, and design of a complete node. In Phase 2 we would build up 3 nodes and evaluate their performance against the current design. If successful this SBIR would make the SDSN even more cost effective, allowing for its use in a much broader range of applications, along with significantly increasing the commercial potential.
