US Navy (USN) researchers, in conjunction with engineers at Northrop Grumman, have cleared a milestone in performing multi-antenna radio operations from a single antenna system, company officials said Monday.

Officials from the US Naval Research Laboratory’s Electromagnetic Maneuver Warfare Command and Control (EMC2) Integrated Topside (InTop) Innovative Naval Prototype directorate, along with industry counterparts at Northrop Grumman, “demonstrated the simultaneous sharing of a single antenna ... performing a mission that would have required multiple dedicated antennas in the past”, by utilising the InTop Low-Level Resource Allocation Manager (LLRAM) programme, company officials said in a 28 October statement.

The test, conducted in September at the laboratory’s test facility in Chesapeake Beach, Maryland, leveraged the LLRAM’s “signal sharing capabilities” coupled with the adaptable antenna size pattern capabilities of the InTop Electronic Warfare/Information Operations/Communications (EW/IO/COMMS) system, to execute the multi-antenna mission from a single antenna.
