For the automatic scaling and analysis of the ionospheric parameters, a method based on the empirical orthogonal function analysis of the ionospheric electron density profiles is proposed in this paper. This method is applied to the measured ionograms of CADI (Canadian Advanced Digital Ionosonde), which is set up at Beijing Space Environment Observation Station (403°N, 1162°E).

By improving and rebuilding the previous mid-latitude model, we extend the model to high latitude and low latitude, respectively. The extension to high latitude mainly includes the effects of convection electric field and particle precipitation. The low-latitude extension primarily takes account of the configuration of magnetic field and interhemispheric coupling.

在对原有中纬电离层模型改造和重建的基础上，将该模型分别向高纬和低纬扩展，模型向高纬的扩展主要考虑了对流电场和粒子沉降的影响，模型向低纬扩展主要考虑了磁场位形、共轭半球的影响。

In the short wave Ionized layer reflection channel, the tropospheric scatter channel, and the moves channel, the clear channel and so on in the actual channel, because of the cloud layer%26rsquo;s, the sierra%26rsquo;s and numbers of high-rise construction%26rsquo;s influence in the city, it can produce the multi- diameters fading, causes the serious mark disturbance, and will limit the speed of the intelligence transmission.
