A method is provided for selectively, dynamically and adaptively jamming the third-party radio communications that are external to a radio communication network to be protected, which optimizes the effectiveness of the jamming of P predefined areas or positions in a network of transmitters, and which uses closed-loop control to limit fratricidal effects on certain platforms having telecommunication transmitters/receivers to be preserved.
