Leidos has won a $14 million contract from the Defense Advanced Research Projects Agency (DARPA) to provide research and development in support of Phase 2 for the Shared Spectrum Access for Radar and Communications (SSPARC) program.

The contract has an eleven month base period of performance, an eleven month option, the company announced Tuesday.

The SSPARC program seeks to improve radar and communications capabilities through spectrum sharing. In Phase 1 of the SSPARC effort the Leidos team proved, via a high-fidelity end-to-end simulation, that the minimum distance from military radar that commercial wireless may operate can be reduced 50x.

Two innovative interference mitigation mechanisms, coordinated frequency hopping and mainbeam avoidance were developed to allow shorter minimum stand-off distances.

In Phase 2 of the contract, Leidos will perform laboratory testing and a field demonstration to validate the technology using real-time software with physical radar and communications systems.

If successful, the algorithms developed will allow increased radio frequency spectrum availability for both radar and communications systems, which is currently a significant operational constraint.
