End-to-End BMDS Interceptor / Ground Terminal Communication Links

Welkin Sciences proposes to develop the Interceptor Missile Communication Relay Architecture (IMCRA), a hardened communication network specifically tailored to support robust data communication between a ground terminal and interceptor missiles under severe war-time environments. IMCRA is an extension of the Advanced Interceptor Data Link (AIDL) currently under development by Welkin Sciences. The AIDL itself is a very robust upgrade to the current In-flight Interceptor Communication Systems (IFICS). The AIDL employs several mitigation design techniques that harden the data link to radiation, EMP, channel fading and jamming. The proposed IMCRA design employs the hardened AIDL as the direct link between the interceptor an the ground terminal, and adds two relay links specifically designed to support end-game video imagery from the optical sensor of kill vehicle (KV). The various transmitters, receivers and transceivers within the proposed IMCRA design are governed by dynamic parameters that are prescribed to change link characteristics as needed throughout the interceptor fly-out. To support evaluation of the IMCRA design, Welkin Sciences further proposes to upgrade two important development tools: 1) the COMLNK software package, a comprehensive simulation environment used to design strategic DoD modems; and 2) the COMLNK Hardware platform (CHP) that serves as a transceiver prototyping system with which fully operational strategic links can be implemented and tested.
