regardless frequency, light is inherently vulnerable to dissipation than lower frequency radio waves.Anybody know what kind of frequency this system would operate in? Visible light would dissipate very quickly.
so I don't think this thing is aimed at replacing conventional radars, but to complement them. Essentially it is an improvement of existing Optical detectors like IR imagining. Current IR imaging is like mechanical scanning Radar, the proposed device would be Electrical scanned with all advantages that would add.
