Key Technologies Of Anti-ship Cruise Missile Precision Strikes

In order to achieve hit accuracy, the dissertation mainly introduces the anti-ship cruise missile and its guidance model of aerodynamic / thrust vector, path planning algorithms, target detection and identification and some other key issues.Firstly, anti-ship cruise missiles controller design problem is studied, then based on aerodynamic / thrust vector modeling, the nonlinear disturbance observer is introduced to weaken the impact which is caused by the system internal modeling error and outside interference. The missile control system is divided into the fast and slow control system loop, and the two controllers are given separately.In the second part the guidance law for midcourse and terminal guidance of the cruise missiles is studied. The large airspace orbital transfer guidance law is investigated for midcourse guidance. On the research of the terminal guidance, regarding the mobile sector of objectives as a disturbance, we study the fast sliding Adaptive Terminal Guidance Law, which is based on the mathematical model in three-dimensional space fugitives.Then, based on two kinds of different search space, the static and dynamic path planning methods are given. The first method is based on the smallest threat surface PSO route planning method, namely using PSO search for optimal three-dimensional track on the smallest threat surface. The second method is based on the ant colony expansion joints Track Planning Act. Ant algorithm is based on the method that ants foraging characteristics is to find a more effective and feasible optimal path.Following, the moving target detection and multi-sensor data fusion target identification problem is studied when attacking targets under strong interference. The dual-frame differences can effectively detects dynamic target, then based on WNN, we can recognize the target by information fusion on the theory of evidence.Finally, based on Multigen Creator / Vega and VC simulation platform, the 3D animation of anti-ship cruise missile striking at the enemy's combat warships is produced.
