Maritime Intelligence, Surveillance, Reconnaissance (ISR) and Space Exploitation

"Maritime Intelligence, Surveillance, and Reconnaissance (ISR) has been proven critical to national defense. Currently, E-2C, S-3B, P-3C and EP-3 aircraft are used to support the Navy's ISR primary missions. Desires to utilize UAVs have significantlyenabled platform advances, but still demand the development of small low cost, lower power ISR payloads.ALPHATECH and NAVSYS propose to integrate ALPHATECH's Tracking Technology Product (TTP) with NAVSYS' GPS-based Bistatic Sensor, resulting in a Maritime target detection and tracking capability. This system exploits the signal environment originating fromthe existing spaced based GPS constellation and can directly take advantage of anticipated GPS upgrades. The system offers a low cost, low power and inconspicuous ISR solution for Maritime applications. The proposed architecture leverages advances inNAVSYS GPS electronics and ALPHATECH multiple hypothesis tracking (MHT) technology.ALPHATECH and NAVSYS will evolve the NAVSYS High Gain Advanced GPS Receiver (HAGR) into a Maritime Detection, Tracking and Classification system by designing scanning strategies / RADAR modes, a Sensor Report Generator and a target tracker / classifier.The combined system provides maximal processing gains that are both coherent and incoherent via the track before detect algorithms. These processing gains extend the system range and the detectable target set. The proposed technology will help provide USNsurface
