Leidos moves to SSPARC Ph 2
Leidos will work on Phase 2 of DARPA’s Shared Spectrum Access for Radar and Communications (SSPARC) programme under a $14 million contract announced on 3 November.
The SSPARC programme is working to use spectrum sharing to improve radar and communications capabilities.
Under Phase 1 of the programme, 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 interference mitigation mechanisms - coordinated frequency hopping and mainbeam avoidance - were developed to allow shorter minimum stand-off distances.
Phase 2 will see Leidos 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.
John Fratamico, president, Leidos Group, said: ‘We look forward to providing DARPA with real-time radio frequency management expertise to assist with the expansion of spectrum sharing between radar, military radios, and commercial wireless systems.’
