| Our country's cruise missile enterprise had a big disparity with the international advanced level, especially the missile's firing accuracy, although had the big development. As a kind of precise guidance weapon, the guidance technology is important. This thesis intends to realize the missile's firing accuracy by studying scene matching, track following, the middle guidance law and the terminal guidance law.In the second chapter, it proposes a layered planning method based on surface of minimum risk. Introducing the concept of SOMR(Surface of Minimum Risk) forms the search space. And a polynomial function with finite terms is used to approach the XOY projection of 3D route in the SOMR. So the original planning problem is simplified to search the best series of values in the coefficient space of the polynomial function. PSO(Particle swarm optimization) is introduced to obtain the suboptimal route. Then we can obtain an optimal route with some modification.Currently, scene matching has been used to aid track following. So it proposes two Anti-Rotation feature matching methods which get good performance particularly in route control. In the third chapter, genetic algorithm, PSO and global search are introduced to do matching in two sized base-image. Results provide that every algorithm has advantage and disadvantage, but all have Anti-Rotation performance.A good many missiles not only hope to obtain slight miss distance, but also hope the best posture when attacking target. In this way, the warhead will display the biggest efficiency, and obtain the best execution. In the fourth chapter, it proposes a Variable Structure Terminal Guidance Law in Posture Restraint Trajectory Based on GA, which can better meet requirements above. It also do studies in neural network guidance law and fuzzy guidance law.Finally this thesis realizes 3D animation simulation of cruise missile's attacking target with VC++ and Multigen Creator/Vega.
