A towed decoy arrangement for a craft with a decoy towed by the craft. Threatening signals are received by the craft and a noise signal is generated which is converted up to a frequency which is rapidly attenuated in air and sent to the towed decoy. In the decoy, the received signal is transformed into the noise signal by shifting it to the frequency of the threatening signal. Then the signal is transmitted from the decoy.

The invention claimed is: 1. A towed decoy arrangement for a craft comprising a decoy towed by the craft, said craft having a first antenna for receiving threatening signals, an analysis and noise signal generating device which generates a noise signal and converts said noise signal up to a frequency which is rapidly attenuated in air and a second antenna for transmitting said noise signal to the towed decoy, said decoy including a third antenna receiving the signal from the second antenna of the craft, a device transforming the received signal into a noise signal by shifting said received signal to the frequency of the threatening signal and amplifying said received signal, and a fourth antenna transmitting the noise signal in the direction of the source of the threat signal. 2. The towed decoy arrangement as claimed in claim 1, wherein the analysis and noise signal generating device includes jamming equipment of the aircraft. 3. The towed decoy arrangement as claimed in claim 2, wherein the noise signal between the craft and decoy is higher than 58 GHz. 4. The towed decoy arrangement as claimed in claim 1, wherein the noise signal between craft and decoy is higher than 58 GHz. 5. The towed decoy arrangement as claimed in claim 4, wherein the noise signal between craft and decoy is 77짹5 GHz. 6. A method of improving a towed decoy arrangement for a craft towing a decoy and having equipment for receiving threatening signals, for analysing the same and generating a noise signal and for transmitting the noise signal, said method comprising the steps of: providing the craft with an antenna for receiving the threatening signals; generating, with an analysis and noise signal generating device, a noise signal and converting the same up to a frequency which is rapidly attenuated in air; transmitting said noise signal to the towed decoy; receiving, by the decoy, the signal transmitted from the the craft; transforming the received signal into a noise signal by shifting said received signal to the frequency of the threatening signal; and transmitting, by the decoy, the noise signal in the direction of the source of the threat signal. 7. The method as claimed in claim 6, wherein the step of generating uses the jamming equipment of the aircraft. 8. The method as claimed in claim 7, wherein the noise signal between the craft and decoy is selected to be higher than 58 GHz. 9. The method as claimed in claim 6, wherein the noise signal between the craft and decoy is selected to be higher than 58 GHz. 10. The method as claimed in claim 9, wherein the noise signal between the craft and decoy is selected to be 77짹5 GHz. 11. A towed decoy arrangement comprising a craft towing a decoy, said craft including an antenna for receiving threatening signals and for sending signals, an analysis and noise signal generating device which generates a noise signal and converts the same up to a frequency which is rapidly attenuated in air, said craft transmitting said noise signal to the towed decoy, said decoy having an antenna for receiving the signal from the craft and a device for transforming the received signal into a noise signal by shifting said received signal to the frequency of the threatening signal, said decoy amplifying and transmitting said noise signal in the direction of the source of the threat signal. 12. The towed decoy arrangement as claimed in claim 11, wherein the analysis and noise signal generating device includes the jamming equipment of the aircraft. 13. The towed decoy arrangement as claimed in claim 12, wherein the noise signal between the craft and decoy is higher than 58 GHz. 14. The towed decoy arrangement as claimed in claim 11, wherein the noise signal between the craft and decoy is higher than 58 GHz. 15. The towed decoy arrangement as claimed in claim 14, wherein the noise signal between craft and decoy is 77+/-5 GHz.
