将分布估计算法引入到巡航导弹航迹规划中,以期在较短时间内规划出性能指标最优的攻击轨迹,提高巡航导弹的作战效能。在分布估计算法的应用过程中,首先采用航路段等距分割建立航迹规划优化性能指标的离散化计算方法;其次引入坐标变化和候选节点构建基于分布估计算法的航迹规划方法;最后,以多核处理器提供的并行计算能力为依托,进行了航迹规划方法的并行计算设计。仿真实验表明,该方法能有效地缩短优化时间,提高优化结果。

In order to get a best attack path in a short time so as to improve operational efficiency of cruise missile,we introduced a new method,Estimation of Distribution Algorithm(EDA),into path planning.In the application of EDA,we used air route equidistant partition to set up a discrete method for calculating optimized performance indexes of the path planning.Then,we introduced coordinate transformation and candidate nodes to build an EDA-based path planning method.Based on parallel computation ability provided by multi-core processor,we implemented multi-core parallel computing for the path planning method.Experiments showed that the method could shorten the optimization time and improve optimization result.
