The Department of Defense (DOD) is seeking proposals for the topic "DIRECT TO PHASE II: Modernized Sonar Transmit Electronics" as part of the SBIR program. The Navy branch is specifically interested in developing an architecture for modernized digital transmit electronics to power future hull-mounted acoustic arrays within the AN/SQQ-89A(V)15 sonar system. The current transmit electronics for the AN/SQS-53C have reached end of life and need to be modernized. The Navy desires prototype transmit electronics that can transform digital waveforms into voltage signals at individual TR-343 transducers while fitting within the existing analog power transmit capability. The project duration is divided into phases, with Phase I focusing on developing a concept and architecture, and Phase II involving the development and delivery of a prototype. The final Phase II report should include a design for scaling the prototype to accommodate a full AN/SQS-53C transducer set. The technology developed under this effort has potential applications in commercial sectors such as the oil and gas industry. The project is open for proposals until June 12, 2024, and more details can be found on the grants.gov website.
