Study Of The Fuze-warhead Coordination Of Laser-fuzing Fragmentation Warhead Anti-aircraft Missile

In modern warfare,there are more and more threat from the air,including a wide variety of jets,helicopters,unmanned aerial vehicles and various types of tactical and strategic missiles.Because of the promotion of targets in velocity,structure strength and stealth performance,it is vital to study the Fuze-warhead Coordination theory for the anti-aircraft missile.Firstly,a mathematical model for laser-fuzing fragmentation warhead missile is establish,including the engagement of missile and target,laser fuze detection,target vulnerability characteristics warhead destruction area;In order to highlight the importance of the damage effects of the anti-aircraft missile,this paper estimates the warhead power of common anti-aircraft missiles.A new speed coordinate system of central fragment was proposed to simplify the calculation of target killing element in the process of regional coverage;Then the research of optimal initiation delay were studied under the system of ground control station guided anti-aircraft missiles and the guidance integrated fuzing anti-aircraft missile.Then this paper introduces the directional warhead briefly.Chose one of the directional warhead to improve the structure.That leads to an improvement of a three-dimensional control in optimum initiation azimuth angle.By calculating the optimal initiation delay and the optimum initiation azimuth angle and the angle between the central fragment and the target,the improved directional warhead has a promotion in the damage ability.Research work in this paper has some theoretical and practical significance for the design of anti-aircraft missile in the future.
