An inversion method of anomalous atmospheric refractive environment

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%.
