摘　　要：雷电定位算法直接影响着雷电定位的结果。针对传统雷电定位算法易发散、迭代次数多、定位精度低的情况,基于波导模理论,提出了一种基于波导模理论与果蝇算法(Modified Fruit Fly Optimization Algorithm,MFOA)的雷电甚低频定位研究技术。在探测站与雷电位置距离较远的时候,采用甚低频电磁波在空气中传播的相速、群速,修正算法中的光速,更接近电磁波在空气中传播的真实速度,提高定位的精确度。通过仿真的结果表明,该方法能快速收敛、跳出局部最优,定位精度高。The lightning positioning algorithm directly affects the results of lightning positioning. Based on the waveguide model theory,a lightning VLF localization technique based on waveguide mode theory and drosophila algorithm( Modified Fruit Fly Optimization Algorithm,MFOA) is proposed. When the detection station is far away from the lightning position,the phase and group speeds of very low frequency electromagnetic waves propagating in the air are used instead of the speed of light in the algorithm,which is closer to the true speed of electromagnetic waves propagating in the air and improves the accuracy of positioning. The results from the simulation show that the method can converge quickly,jump out of the local optimum,and has high positioning accuracy.
