frequency sounding at oblique incidence

The oblique sounding is one of the powerful tools,by which an oblique ionogram is obtained with the group path or time delay against operating frequency.

斜向探测是电离层探测的主要方式之一,它能够获得电波传播群时延和频率关系的电离图。

For that reason,it should analyze and handle three important parameters of radar work:environmental conductivity,dielectric constant and surveying frequency.

为此,必须分析、掌握雷达工作的三个重要参数:环境电导率、介电常数和探测频率。
