RF decoy and method for deceiving radar-based missiles
First Claim
1. A stand-alone airborne RF decoy adapted for protecting an airborne platform against multiple enemy radar-based threats, said airborne RF decoy comprising:
- (i) means for receiving a plurality of radar signals from one or more directions;
(ii) means for storing said plurality of radar signals;
(iii) means for analyzing said plurality of radar signals to identify threat parameters;
(iv) means for altering said plurality of radar signals in order to deceive said multiple enemy radar-based threats;
(v) means for transmitting the altered radar signals;
(vi) an independent power supply source;
(vii) an external form of a standard chaff decoy or a standard flare decoy so that the airborne RF decoy can be ejected from the airborne platform via a standard housing of chaff or flare dispensers; and
(viii) vertical and horizontal wings that are opened automatically immediately after ejection from the airborne platform, followed by a pyrotechnic mechanism that brings the wings to their final position so that the airborne RF decoy achieves aerodynamical stability.

Abstract
An expendable, stand-alone, off-board Electronic Counter-Measure system, airborne RF decoy aimed to provide airborne platforms with protection against multiple radar-based threats including Air-to-Air and Surface-to-Air missiles both active and semi-active ones. The airborne RF decoy has the mechanical outline of standard chaff and flare decoys and is safely ejected from any platform by pyrotechnic elements. The airborne RF decoy deceives enemy radar-based threats as follows: immediately after its ejection from the protected airborne platform, the decoy activates an energy source, stabilizes its path, acquires illuminating signals and analyzes threat parameters. Then the decoy alters the received signals to generate an authentic false target and transmits a deceiving signal towards the radar threat. The radar threats locks on the decoy and follow its path. Thus the threat course is diverted from the protected airborne platform and a large miss distance of the attacking missile (tens to hundreds of meters) is assured.
