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.
