摘　　要：结合定频和扫频探测的特点,提出了一种新的探测模式——跳频探测,它可以用于对电离层局部频率精细结构的研究,也可以用于全频段电离层概貌的获取。单站电离层探测系统利用跳频探测模式实现的探测结果表明:在自动跳频探测模式设计中,采用的多线程技术可以很好地实现探测系统硬件控制、数据处理、信息提取与显示、人机交互和自动探测功能,满足探测的实时性要求。同时,采用Matlab引擎技术完成跳频探测数据的处理和显示,使软件获得强大的数据处理和显示能力,并具有开放性,易于升级。A new sound mode called auto hopped frequency sound （AHFS） is present in this paper. This sound mode combined characteristics of fixed frequency sound and swept frequency sound, which is useful in ionospheric fine structure research of partial band frequency, and can obtain ionospheric overview of whole band frequency. AHFS adopts the multi-thread technique to meet the real-time requirement and to implement the functions of hardware control, data processing, information extraction and visualization, HMI and sound automation. The result obtained from monostatic ionospheric sounding system using AHFS mode shows good performance. In addition, Matlab engine technique is adopted to implement AHFS data processing and visualization, which bring powerful ability of processing and display to system. Therefore, system is more open and easier to upgrade.
