摘　　要：子午工程二期计划在漠河、北京、武汉、深圳四地分别建设由一个发射站和三个接收站构成的电离层高频多普勒监测台阵.本文介绍了为此研制的电离层高频多普勒监测仪的进展和试观测期间取得的一些观测结果.通过与电离层测高仪进行交叉对比,设备的性能和探测能力得到了验证.目前该设备已部署7个站点进行试观测,本文报告了该设备探测到的太阳耀斑导致的电离层扰动、电离层行进式扰动、大尺度电场导致的多站同时扰动等多种现象.未来子午工程二期建成后,该设备将具备我国上空北至漠河、南至广东的电离层扰动监测能力,并与其它探测手段融合发挥空间天气综合监测网络的最大效能.The Phase II of Chinese Meridian Project plans to construct ionospheric Doppler sounding arrays around Mohe,Beijing,Wuhan,and Shenzhen.Each array consists of one transmitter station and three stations equipped with the ionospheric high-frequency Doppler shift monitor,which is described in this paper in terms of system design and preliminary results from its pilot operation.By comparison with a collocated ionosonde,the performance capability of the sounder is validated.At present,the sounders have been installed at seven stations and have been running continuously for about 1 year.This paper presents observations of various ionospheric disturbances caused by solar flare eruptions,travelling ionosphere disturbances,and probable large-scale electric field variations.Once established,the chain of sounder arrays will continuously monitor ionospheric disturbances over eastern China and contribute to the sophisticated space environment monitoring network of the Chinese Meridian Project.
