Based on the globally and rapidly developing microwave-­photonics approach that has already found its application in the promising radio-­electronic means of telecommunications, radars, electronic countermeasures, security, computing and measurement equipment, this article proposes a new development principle for the group and individual radio-­electronic protection facilities against the remote effect of unauthorized radio channels for various purposes. Its key advantages include simplicity and insensitivity to electronic interference, including intentional ones, as well as ultra-fast ultra-wideband processing of any radio-frequency signal received in an optoelectronic processor that depending on its purpose, either increases the group or individual protection area up to several kilometers, or reduces the response time for individual protection to a hundred of nanoseconds , while ensuring operation over the entire operating frequency band. The diagrams of optoelectronic processors, description of developed radio-frequency electronic protection samples with the spoofing or blocking functions for unauthorized radio channels, and the results of laboratory and preliminary field tests are provided.
