The Multiple Vehicle Communications System (MVCS) allows Littoral Combat Ship (LCS) Mission Packages to simultaneously communicate with multiple Unmanned Surface Vehicles (USVs) and surfaced Unmanned Underwater Vehicles (UUVs) by providing a common data link and network communication services. The MVCS is designed as an open architecture communications system that can be adapted to support any radio. However, current communications equipment does not meet the requirements that all radios must be JTRS compliant and mission packages must be able to operate in a jammed environment. An innovative anti-jam waveform is needed to meet the MVCS requirements. IAI and its collaborator, Harris Corporation will design and develop JARNET, a Jamming Resistant Networking technology, that supports communications between USVs and LCSs under a variety of jamming conditions, including continuous wave, pulsed and broadband noise. JARNET combines spectrum sensing, capacity-approaching channel coding, spectrum spreading, and adaptive modulation to maximize spectrum utilization under various channel conditions in the presence of jamming. JTRS requires the waveform to be implemented in software so that it can operate on any JTRS compliant software defined radio. This allows the waveform to be widely used in both military and commercial applications. The anti-jamming technology can be used in any wide bandwidth wireless networks, such as police, civil defense, search and rescue, and industrial applications.
