US Patent 7667634 Active RF decoy simulation apparatus

RF decoy anti-missile testing in a virtual environment through simulating the aviation of a missile, the reflected signal of a target, and an active RF decoy by use of a target motion simulator which implements the moving trajectory of the RF decoy. The RF decoy radiates a reflected signal of the target and also a deception signal through use of a microwave device that transfers the detected signal from the missile and amplifies the received signal so that a repeated delay signal of the RE decoy greater than that of the reflected signal of the target is radiated by the target motion simulator, thereby testing the deceit performance of the decoy.
