The Phase 1 SBIR project addressed a significant vulnerability of the SeaLancet RT-1944/U Communication System: its susceptibility to jamming. This vulnerability can affect the ability of the Navy to provide Mine Countermeasures because the SeaLancet is being used as part of the Mine Countermeasures Mission Package in the Littoral Combat Ship (LCS) Program. The overall objective of this Phase II effort is to develop and demonstrate an operational prototype of an Anti-Jam (AJ) phased array antenna for the RT-1944/U capable of operation and deployment with the Remote Multi-Mission Vehicle (RMMV). The following technical milestones have been identified: 1. Finalize the integration strategy for the RMMV. 2. Integrate the noise monitoring receiver and signal processing hardware required for anti-jam capability into the FCI-3740 antenna head. 3. Refine anti-jam algorithms that were developed in Phase I and produce production code. 4. Extend the frequency range of the FCI-3740 antenna head to match the range of the RT-1944/U radio. 5. Repackage the FCI-3740 hardware for the NAVSEA environment and mission. 6. Demonstration in a relevant environment. The objective of the Phase II Option is to enable Anti-Jam capability to the other end of the communications link, that of the attendant LCS.
