利用微机对电离层频高图读图及月报表的自动处理

Auto—Processing of Ionograming and Monthly Parameter Tables by a Microcomputer

前言电离层是近地环境的一个重要层次,目前对它的研究方法主要是地面垂直探测,然后在胶片上记录下回波描迹,即频高图。从频高图上可以读取电离层的十四个特征参数:f_0F_2,h′F2,M(3000)F2,f_0F1,h°F,M(3000)F1,f_0E,h′E,f_0E_(?),h′E.,E.TYPE,f_bE.,f_(min),f_x1。再将这些参数位制成月报表,供研究人员使用。以前判读频高图和制作月报表是靠人工完成,工作量大,规则多,容易出错,精度较差。为此,我们研制了这套程序。它利羽微机控制,从原始频高图的判读,直到做出月报表,除人工识别参数输入外,基本上实现了全套自动化,大大节省了人力,提高了读图的精度和计算的准确性。

Parametering the ionograms and making the monthly tables by hand are a time—and man- power—consuming work.So we invented this set of software in which there were five Programs. The first program connects a computer and a digitizer which transfers the data from the iono- grams to the computer.The second mabes the data ready to be used by the third program which directs the computer to calculate the data and make the monthly parameter tables.The fourth is to print these tables according to the standard format.And the fifth is to plot the curves and schemes needed.Comparison showed that,When this system was used,the efficiency increased by a factor of 8 and the precision also increased considerably.
