Missile Ballistic Design And Strike Planning Technology Research

With the development of information technology and intelligence technology,the combat mode of traditional munitions can no longer meet the combat mission requirements of modern warfare,and the munitions gradually develop from a single destructive function to an intelligent direction with detection,identification,networking and clustering,etc.Intelligent munitions also become a major force in the battlefield because of their unique advantages in tactical applications such as inspection and attack,saturation attack,etc.Therefore,the research on intelligent munitions has a Therefore,it is of great value to conduct research on intelligent munitions.In this paper,we take cruise missiles as the research object,carry out research on missile trajectory planning and guidance law design,and further explore missile trajectory planning methods and multi-munition cooperative combat target assignment techniques to improve the strike effectiveness of smart munitions in modern warfare.The main research works are as follows:Firstly,the common coordinate system of cruise missile and the conversion relationship between coordinate systems are defined,and the force and motion of the missile are analyzed theoretically to construct a rigid body six-degree-of-freedom ballistic mathematical model.Based on the analysis of the basic shape and aerodynamic parameters of the cruise missile,the ballistic design model is simulated numerically,and the design study of the fixed height cruise guidance law and terminal guidance law is completed based on the BTT control method to realize the strike tracking of the target.Second,the application of missile trajectory planning methods is further explored on the basis of missile trajectory design.It revolves around planning an effective optimal trajectory for a missile in a static environment based on known environmental information.Combining the performance constraints of the munition itself and the analysis of static environmental information,the trajectory planning problem is transformed into a mathematical model,and the RRT* algorithm is chosen to design the trajectory planning scheme,which is improved by adaptively adjusting the step size,extending the node bias sampling,and bi-directional tree search to improve the features of the RRT* algorithm such as search blindness and slow convergence speed in path planning seeking,and under the constructed environmental model The effectiveness of the improved algorithm is verified in the constructed environment model.Finally,the multi-bomb coordinated strike target allocation problem is described and analyzed,and the battlefield design is based on the preset battlefield environment and other situational information,and the static threat assessment and dynamic threat assessment of the combat environment are combined with the hierarchical analysis and entropy method,respectively.
