The Department of Defense (DOD) is seeking proposals for a Small Business Innovation Research (SBIR) program, specifically for Phase I of the STTR program. The topic of the solicitation is "Scalable High Frequency Transmit/Receive Array for Multiple Unmanned Underwater Vehicle and Torpedo Applications". The Navy branch of the DOD is interested in developing a configurable, scalable, adaptable, and affordable High Frequency SONAR array technology based on efficient and affordable textured ceramic materials. This technology aims to improve performance in more compact form factors. The objective is to create a transducer concept that can be used for both legacy acoustic communications and heavyweight torpedo detection and homing applications. The Phase I project should demonstrate a robust, manufacturable, and affordable design for individual transducer elements that can be considered for both legacy UUV and heavyweight torpedo applications. Phase II involves constructing an HF array of such sensors suitable for a specific application, evaluating the cost and performance envelope made possible by the innovative application of textured ceramics. Phase III aims to deliver an affordable and fundamentally new performance capability for both commercial and Navy/Marine Corps high frequency SONAR and acoustic communications. The project duration is not specified, but the solicitation is closed. For more information, visit the SBIR topic link or the solicitation agency URL.
