A method for detecting electromagnetic threats to an aircraft, wherein electromagnetic fields are measured, and in the case of an arising threat to the aircraft being detected, countermeasures are taken, characterized by the following steps: measuring the frequency and the amplitude of at least one electromagnetic field in the frequency range from 9 KHz to 40 GHz; analyzing the measured results and determining the field intensity in relation to each measured frequency; comparing the field intensity in relation to each measured frequency with stored limiting values or qualification values, wherein the aircraft is qualified for field intensities that are lower than the limiting values; and providing the result in the form of a warning signal in the case of approaching or exceeding a limiting value.

1. A method for detecting electromagnetic threats to a helicopter during an in-flight mode of the helicopter, wherein the helicopter is qualified for in-flight electromagnetic intensity qualification values, the method comprising: detecting at least one electromagnetic field external to the helicopter, in a frequency range from 9 KHz to 40 GHz, and in a frequency bandwidth of substantially 40 GHz corresponding to the frequency range using at least one antenna externally affixed to the helicopter;measuring frequency and amplitude of the at least one electromagnetic field and analysing the measured results and determining a field intensity in relation to each measured frequency using a high-intensity radiated field (HIRF) processor on-board the helicopter and in communication with the at least one antenna;comparing the field intensity in relation to each measured frequency with stored electromagnetic intensity limiting values using the HIRF processor, wherein the limiting values are lower than the qualification values; andproviding the result of the comparison from the HIRF processor in the form of a warning signal in the case of the field intensities approaching or exceeding one of the limiting values. 2. The method according to claim 1, further comprising detecting direction of the at least one electromagnetic field. 3. The method according to claim 1, wherein a single antenna is used for detecting the at least one electromagnetic field, in at least the entire frequency range from 9 KHz to 20 GHz. 4. The method according to claim 1, further comprising displaying or indicating the field intensity in relation to each measured frequency in comparison to the limiting values of the helicopter. 5. The method according to claim 1, wherein the case of the field intensities approaching or exceeding the limiting values, a warning of an acoustic and/or visual type takes place. 6. The method according to claim 1, further comprising drawing an electromagnetic map of a specified region based on the field intensity in relation to each measured frequency. 7. A sensor system for detecting electromagnetic threats to a helicopter during an in-flight mode of the helicopter, wherein the helicopter is qualified for in-flight electromagnetic intensity qualification values, the system comprising: at least one antenna externally affixed to the helicopter for detecting at least one electromagnetic field external to the helicopter, in a frequency range from 9 KHz to 40 GHz, and in a frequency bandwidth of substantially 40 GHz corresponding to the frequency range; anda high-intensity radiated field (HIRF) processor on-board the helicopter and in communication with the at least one antenna for measuring frequency and amplitude of the at least one electromagnetic field and analysing the measured results and determining a field intensity in relation to each measured frequency, for comparing the field intensity in relation to each measured frequency with stored electromagnetic intensity limiting values using the HIRF processor, wherein the limiting values are lower than the qualification values, and for providing the result of the comparison in the form of a warning signal in the case of the field intensities approaching or exceeding one of the limiting values. 8. The system according to claim 7, wherein detection of the direction of the electromagnetic radiation at least two antennae or field-intensity measuring sensors that are separate from each other are used. 9. The system according to claim 7, further comprising at least two antennae of the same type, which are affixed to different installation locations of the platform of the aircraft. 10. The system according to claim 7, further comprising means for electronically recording or storing geo-referenced field-intensity mapping. 11. The system according to claim 7, further comprising a display device for showing the relevant electromagnetic field information.
