摘要: 提出一种基于不同威胁体的路径规划新方法。从理论上建立了具有不同威胁体的局部空域路径选择原则,给出了根据不同威胁体建立相应路径图的步骤和方法。描述了基于图形模型的进化优化算法,并应用此算法进行了路径优化。进行了仿真验证,仿真结果表明,提出的路径规划方法不仅可行,而且有效地突破了原Voronoi 图只能对相同威胁体进行路径规划的局限。

Abstract: A path planning scheme based-on different threats for unmanned combat air vehicles is developed. Firstlythe principle to select path in local area with different threats is established, and a new approach to create the pathdiagram by different threats is presented. Secondly the evolutionary algorithms based-on graph model is described.Results of simulation show that this path planning method can be used to generate an optimal path without smoothness. Thus a breakthrough has been made for the initial path planning by using the Voronoi diagram only for samethreats.

Key words: path planning, unmanned combat air vehicles, graph model, evolutionary algorithms
