文献[1]提出了一种基于HF返回散射和斜向探测联合探测电离层,融合两种探测结果联合反演电离层参数的新方法,该反演方法基于特定的电离层QP模型和均方误差最小准则,采用全局搜索的方法确定QP模型参数。针对该联合反演方法进行了改进,分析了不同采样方式对于反演结果的影响,通过优化频点选择提高了反演的稳定性和准确性,并引入了粒子群优化算法进行搜索,大大缩短了反演的时间。仿真结果显示,这种改进后的联合反演算法具有更高的效率和实用性。

A new technique for detecting the ionosphere by the combined use of HF backscatter and oblique sounding,and a new method for the inversion of the ionospheric parameters by the association of the two kinds of ionogram are developed in Ref.[1].The inversion method is based on the quasi-parabolic ionosphere model and least-mean-squares error criterion,the global searching method is adopted for determination of the quasi-parabolic parameters.The method has been improved.The influence of different sampling styles on inversion has been analysed,the stability and accuracy can be improved by using the optimum frequency point.The time of inversion is reduced by introducing PSO.The emulation results show that this improved method demonstrates highly efficient and practicable.
