Unmanned aerial vehicle decoy-resistant flight path control method based on active and passive composite guidance

Abstract

The invention relates to an unmanned aerial vehicle decoy-resistant flight path control method based on active and passive composite guidance, and the method comprises the steps: entering a flight path tracking control stage when an unmanned aerial vehicle climbs to a specified flight height; performing distance estimation in a satellite navigation / inertial navigation / voyage calculation or integrated navigation mode, and when the distance is smaller than the detection and tracking action distance of the unmanned aerial vehicle passive guide device, entering a passive search stage; when an unmanned aerial vehicle passive radar seeker intercepts and tracks a target or bait, entering a passive guidance tracking stage; when the distance between the unmanned aerial vehicle and the center pointT of the target position is smaller than the range of the active radar recognition and tracking action distance of the unmanned aerial vehicle, enabling the unmanned aerial vehicle to enter a strabismus flight active search stage; and after the unmanned aerial vehicle recognizes that the target is a real target, enabling the unmanned aerial vehicle to enter a front-view attack stage, determining whether the unmanned aerial vehicle meets a diving attack condition or not according to the active and passive composite guide information, and if yes, enabling the unmanned aerial vehicle quickly to enter diving to strike the target.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle track control, and in particular relates to an active-passive composite guidance anti-bait track control method of an unmanned aerial vehicle. Background technique [0002] Modern advanced air defense system radars are generally equipped with active decoys to resist anti-radiation attacks. Traditional reconnaissance and attack drones are easily attracted by decoy targets, which greatly reduces their combat effectiveness, especially for precision-guided attack drones. , once it is lured away, it will not be able to exert its ability to destroy the target. The anti-bait problem of the target has become an important problem restricting the detection and strike of the UAV. [0003] The existing UAV anti-bait methods mainly use active-passive composite and other multi-mode guidance technologies to improve the ability to identify radar targets and decoys in complex electromagnetic environments. ...
