Jamming device and jamming method

A jamming device for jamming a frequency hopping signal, the jamming device comprising:

• at least one receiving antenna configured to receive signals in the signal spectrum of the frequency hopping signal;
• an emission detection unit configured to detect emissions in the received signals that possibly pertain to the frequency hopping signal;
• a signal analysis unit configured to analyze the detected emissions for determining characteristic properties of the frequency hopping signal in an analysis mode and configured to output corresponding jamming trigger signals in an active jamming mode if detected emissions pertain to the frequency hopping signal;
• and
• a signal jamming unit configured to jam in the active jamming mode the relevant emissions with a predictive jamming scheme based on the jamming trigger signals if the jamming trigger signals are available and based on a reactive jamming scheme or a barrage jamming scheme if the jamming trigger signals are not available,
• wherein the emission detection unit is configured to provide the signal analysis unit with frequency information about detected emissions, and the signal analysis unit comprises a channel extraction unit, the signal analysis unit is configured to extract from the received signals the signals in frequency ranges of the detected emissions for analyzing the single detected emissions,
• the signal analysis unit comprises a signal type determination unit configured to analyze if a detected emission corresponds to a predetermined emitter and analyze one of the timing sequence or frequency sequence of the detected emissions that corresponds to the predetermined emitter, and
• the signal type determination unit is configured to determine a modulation scheme of the detected emissions used by an emitter for the frequency hopping signal and to discard all emissions that comprise another modulation scheme than the frequency hopping signal.
