OBJECTIVE: To develop a Link-16 receiver capable of simultaneously receiving 4 nets and scalable to more

DESCRIPTION: Link-16 is the workhorse multi-national, interoperable tactical data link for DoD and Coalition combat operations worldwide. Due to the critical need for secure, interoperable data communications, multiple Link-16 TDMA shared, frequency-hopping nets are operational in every theater of operation. The analog RF front-end designs currently limit each unit to receive a single net, forcing federated designs for multi-channel Link-16 terminals and monitoring systems. The currently planned Modernization of Link-16 program envisions Concurrent Mutli-Net (CMN) Operations. Terminals will be required to support at least 4 nets operating simultaneously.
This topic seeks innovations in multi-net hardware in order to provide an affordable solution for a 4-simultaneous -net Link-16 receiver. The solution must be scalable to a higher number (10�s) of nets to meet future requirements. Responses proposing straightforward extensions of current hardware solutions will not be considered acceptable. The preferred solution will replace the current analog L-band RF components, including the hopping LO, with a direct to digital, wideband front end, followed by digital circuits to separate and dehop the overlapping signals. Of particular interest are solutions that also allow the entire Link-16 network to be monitored by one integrated unit.

PHASE I: Develop a receiver architecture design for a multi-net Link-16 receiver. If a hardware demonstrator cannot be built on the budget of a phase 1 and in the first 6 months, the proposer shall complete and submit a credible estimation of the performance, size, power consumption, and cost of imagined hardware.

PHASE II: Build and demonstrate a prototype 4-net receiver. Deliver a 4-net receiver for test and evaluation by PMW150.

PHASE III: Develop multi-net Link-16 receivers and network monitor products.

PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: This technology will find use in commercial satellite and wireless communications.
