无人机末端机动规避中远距空空导弹策略

To address the issue of evading a medium-long range air-to-air missile in beyond visual range (BVR) air combat,a feasible maneuver strategy for unmanned aerial vehicle (UAV) possessing the capability of high overload lateral maneuver within a short period of time to evade the medium-long range air-to-air missile in terminal guidance is proposed based on the characteristics of UAV equipped with lateral rocket boosters. A model of UAV and medium-long range air-to-air missile is established. The influences of lateral overload activation time,lateral overload size and lateral overload direction on the miss distance of a missile are investigated. The experimental results show that the UAV utilizes the maximum available lateral overload within the sustainable time to evade the air-to-air missiles. When a missile is approaching head-on,UAV climbs to evade it,while the same direction climbing and diving maneuvers are used to against the missile approaching from the front.
