Patent ID: 8681218

Claim:
A system for providing RF spatial awareness of an environment, comprising: a) a passive RF detection system operational in a receive-only fashion, comprising: i) an antenna array for receiving RF signals originating from each of a plurality of RF sources; and, ii) a receiver system operatively connected to said antenna array using digital beamforming (DBF) techniques for processing said RF signals and providing measurements of said RF signals as output, wherein a scan pattern is variably controlled; and, b) a control system for receiving said measurements of said RF signals and displaying a plurality of indicia indicating said RF sources on a see through display, thereby providing a visualization of the otherwise invisible RF sources in the field of view, wherein said plurality of indicia convey information regarding the detected sources by their appearance and, wherein said control system allows selection of a subset of RF sources to display as said indicia and allows selection of a related display format.
