      An inversion method of anomalous atmospheric refractive environment

      • 摘要: 针对反常传播中的水平不均匀大气折射率环境反演问题,提出了一种用于跨海微波超视距远距离电路观测场景和信息的反演方法。该方法基于原理要求的全面分析,用粒子群算法进行优化实现反演,确定了海岸-海面-海岸下垫面和近海面复合大气剖面模型,给出了粒子群算法的剖面参数粒子、搜索空间、搜索方法以及适用的适应性函数。研究结果表明,本文方法能够有效反演出水平均匀和不均匀大气环境,且反演结果具有实测剖面的特征,在研究场景中贴地波导高度的误差可低至9.4%。

         

        Abstract: The atmospheric refractive environment inversion of anomalous propagation is investigated, and an inversion method of horizontal inhomogeneous anomalous atmospheric refractive environment is proposed which is suitable for the scenario of cross-sea long distance trans-horizon microwave transmission link. Based on the requirements of principles, particle swarm optimization algorithm is chosen to realize the inversion. The terrain and hybrid atmospheric profile model are determined, and the profile parameters as particles, the search space, search method of the particles and the fitness functions are given. The results show that the method can inverse horizontal homogeneous and inhomogeneous atmospheric refractive environment effectively, and for the scenario studied, the error of the inversed average duct height of the inhomogeneous surface duct is 9.4%.
