Abstract

Abstract:

It is a vital technology for combat aircrafts to apply evasive maneuver and chaff centroid jamming collaboratively to reduce the threat from incoming air-to-air missiles. In order to escape from the radar track beam of missiles as soon as possible, we define the “Maximum normal acceleration of the track beam border” as the principle for evasive maneuver, and the stress analysis is carried out on the aircrafts before the corresponding maneuver strategy is acquired. We establish the aircraft-missile-chaff relative motion model, chaff motion and RCS dynamic change model, construct the chaff flare strategy which conforms with the principle of centroid jamming, and sum up the success of the collaborative application conditions. Simulation result shows that the maneuver is better than the traditional maneuvers and facilitates the pilot operation. When the centroid jamming is applied, the avoid effect is significantly increased with fewer chaff bombs.

Key words: decision theory, evasive maneuvering, beam border, centroid jamming
