摘要
介绍了二维最优信息扩散估计的基本方法,将该方法应用于区域电离层格网模型的建立,实现过程中采用了自适应窗宽和逐级加密的方法改善模型效果,并结合具体算例证明了该模型的有效性。
This paper introduced the basic method of the two dimension optimal information diffusion estimation at first. And then, the paper applied this method to build the region ionospheric grid model. And the ideal result was obtained. In the processing of modeling, the paper adopted the adaptive window width and the encryption step by step method to improve model's effect. At last, this model's effectiveness was proved by specific example.
