本文提出了一种对垂直入射电离图的零星E(ES)层进行自动定标并消除其多次反射和后向散射回波的方法。首先，该方法自动缩放ES层。然后，利用ES层的参数去除Es层多次反射和后向散射的痕迹，以去除VI电离图。利用武汉(30.5°N，114.37°E)记录的电离层图像，与人工比例尺测量的结果进行了对比，验证了该方法的有效性。结果表明，该方法能够实现ES层的自动缩放，有效地提高了酱等人提出的方法的性能。(2013年)。
This paper presents a method for automatically scaling the sporadic E (Es) layer and removing its multiple reflection and backscatter echoes for vertical incidence (VI) ionograms. First, the method scales the Es layer automatically. Then, it removes the traces of multiple reflection and backscatter of the Es layer to clean VI ionograms using the parameters of the Es layer. Ionograms recorded at Wuhan (30.5°N, 114.37°E) are used to verify the performance of the proposed method compared with manually scaled values. The results indicate that the proposed method can automatically scale the Es layer and effectively improve the performance of the technique developed by Jiang et al. (2013).
