The DoD desires innovative prototype solutions for an Autonomous Strategic Force Protection Fiber Optic Sensor Network (ASFPFOSN), a passive opto—acoustic fiber optics sensor system that measures the micro strain of sound waves on continuous wave laser light utilized in a buried fiber optic cable array for detecting intruders into U.S. Navy ports. The technical objective is to assess the capability of opto-acoustics sensing to continually detect light phase shift difference in fiber optics, with the ability through digital signal processing to detect, identify, classify, and locate surface and subsurface targets. This includes the design and development with the possibility of future production.
Existing opto-acoustic sensors available are limited and lag in technologies for surveillance critical to national security. This significant gap in the Defense Industrial Base results in a critical performance gap in the capability of light phase shift differences for localization and correlation in time and space for covert, wide area surveillance and real-time detection of surface and subsurface (e.g. intertidal zone, confined waterways, open water) threats. The ability to detect and target airborne threats is an additional capability of interest.
