With the rapid development of new generation of infrared-guided missiles, it is very difficult for the traditional point-source infrared decoys to confront them. Therefore it is important to research the jamming mechanism and tactical application of infrared decoys. Through the research on rocket-propelled infrared decoys, a movement model and a radiation pattern of partner-fly infrared decoy are established based on the jamming mechanism of infrared centroid effect, the aerodynamics principle as well as the aeronautical dynamics principle. A dynamic simulation seeking superiority is conducted for its firing range and direction, a tactical application method of partner-fly infrared decoy against infrared-guided missile is explored, and the technical conditions of partner-fly infrared decoys are determined.
