Optical Excision Program. Electronic Clipper
Abstract
The ability to significantly reduce the vulnerability of spread spectrum radar communication or intercept systems to narrowband jammer interference has been successfully demonstrated in the laboratory. The interference signal levels were attenuated by the self-adaptive frequency selective limiting properties of an optical processor invented by PROBE SYSTEMS, INC. The key component in these tests was a standard microchannel plate photomultiplier detector that, when exposed to narrowband signals, would saturate and at the same time amplify low-level broadband signals. This electronic clipping of high power spectral density signals was responsible for the successful demonstration of the feasibility of using a microchannel plate photomultiplier for optical excision of interference.
