摘要
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。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模型参数和梯度参数。仿真结果显示,在引入随机误差的情况下,联合反演相比单一手段的反演算法具有更好的反演的效果,能够有效改善反演算法的稳定性。
A new technique for detecting the ionosphere based on the combination of HF backscatter and oblique sounding is presented.The inversion method is based on the quasi-parabolic ionosphere model and least-mean-squares error criterion,and the global searching method is adopted for determining the quasi-parabolic parameters and gradient parameters.The simulation results show that this technique is more accurate and stable than the single-inversion method.
