摘要： The present invention provides a jamming device (100, 200, 300) for jamming a frequency hopping signal (101, 201, 301), the jamming device (100, 200, 300) comprising at least one receiving antenna (102, 202, 301) configured to receive signals (103, 203, 303) in the signal spectrum of the frequency hopping signal (101, 201, 301), an emission detection unit (104, 204, 304) configured to detect emissions (105, 205, 305) in the received signals (103, 203, 303) that possibly pertain to the frequency hopping signal (101, 201, 301), a signal analysis unit (106, 206, 306) configured to analyze the detected emissions (105, 205, 305) for determining characteristic properties of the frequency hopping signal (101, 201, 301) in an analysis mode and configured to output corresponding jamming trigger signals (107, 207, 307) in an active jamming mode if detected emissions (105, 205, 305) pertain to the frequency hopping signal (101, 201, 301), and a signal jamming unit (108, 208, 308) configured to jam in the active jamming mode the relevant emissions (105, 205, 305) with a predictive jamming scheme based on the jamming trigger signals (107, 207, 307) if the jamming trigger signals (107, 207, 307) are available and based on a reactive jamming scheme or a barrage jamming scheme if the jamming trigger signals (107, 207, 307) are not available. Further, the present invention provides a respective jamming method.
