The Simulation Research of IR Decoy Countermeasure to the IR Missile Trace

The model of the movement and the radiation of the IR countermeasure decoy and the model of the movement of the target craft and the infrared missile are set up;The equivalent radiation energy centre of the target craft and the infrared missile is studied.When the infrared missile is tracking the equivalent radiation energy centre,the normal trace of the infrared missile tracking target craft and the countermeasure trace of the infrared missile from the infrared countermeasure decoy are simulated.
