Abstract

In a first step, it is proposed that tunable transmitters and detectors (receivers) be included in a detection system and that a narrowband, preferably variable frequency signal be used in order to determine the frequencies for optimum injection into the electronics of a target. When the detection system identifies these frequencies, destruction can be initiated in the second step of the invention for a transmitter or receiver which is communicating with the target. For this purpose, once the optimum frequencies have been determined, a high-power signal is transmitted into the local area of the target at the specific/determined frequency. The evaluation unit, which is integrated in the detection system, controls the transmission frequencies, evaluates the harmonic signals, selects the optimum frequencies for an attack, and controls and checks the attack process.
