摘　　要：为了解决遥感遥测、自动导航、电子战等领域中常常涉及到障碍物定位问题,在单向抛物方程法的逆算法的基础上提出了双向抛物方程法的逆算法。应用该逆算法对大气波导环境中的障碍物进行了探测和定位,采用插值法分析了大气波导对障碍物定位精确度的影响。仿真结果表明,通过双向抛物方程法的逆算法可以对传播路径上的障碍物进行探测和定位,而且大气折射率变化会对定位精确度产生较大影响。An inverse algorithm of the two-way parabolic equation method is presented based on the inverse algorithm of one-way parabolic equation in order to localize objects in remote sensing,automatic navigation and electronic warfare,et al.It is applied to research the localization of obstacles in atmospheric duct environments.The effects of the atmospheric duct on the accuracy of localization are analyzed by using the interpolation method.The simulated results show that the obstacles on the propagation path can be detected and located by the inverse algorithm of the two-way parabolic equation method,and the atmospheric duct has a major impact on the location accuracy.
