The guidance accuracy of an infrared air-to-air missile is affected by various factors such as target maneuver, interference, and the natural environment. The complicated confrontational environment posed by target maneuver and decoy launch is considered in this article. The more practical adjoint analysis model for the influence of target maneuver and decoy launch on missile guidance accuracy is established by analyzing the jamming process, motion characteristics, and the influence mechanism on the guidance system of point source decoy. By using the adjoint method, the barrel roll maneuver angular rate, the numble of simultaneous decoy launch, the ignition time, the interval between launches and the strategy influence on the miss distance of the missile are analyzed in detail, which will provide strategic references for the aircraft to fight against the infrared air-to-air missiles.
Key words: barrel roll maneuver / decoy launch / strategy / infrared guided missile / guidance accuracy / miss distance / adjoint analysis model
