摘要： 针对在无人作战飞机(UCAV)航路规划中存在的计算复杂和收敛性等问题，该文利用标准粒子群算法原理，在算法搜索过程中引入变异算子，克服了标准算法易陷入局部极值点的不足。利用一组正弦波曲线来构造一个粒子，通过对正弦波个数和幅值的限制，使该方法得到的飞行航路严格经过起始点和目标点，而且满足UCAV的机动性能要求。仿真结果表明该方法简便可行，粒子能较快地收敛于全局最佳航路。

Abstract: For the calculation complexity and the convergence in Unmanned Combat Aerial Vehicle(UCAV) path planning, based on the study on the principles of traditional Particle Swarm Optimization(PSO), mutation operator is presented during the searching process in order to prevent from getting into the local optimum. This paper uses a group of sine waves to construct a parameter, and restricts the number and swing of sine waves. The optimal route can pass the start point and the target point precisely, and is feasible applying to UCAV. Simulation result shows that the method is effective.
