| 摘 要： | 为了研究电离层动力学特性,1985年9月在武汉建成了一个由三个台站组成的高频多普勒台阵和卫星信标法拉第台阵。文中介绍了这个台阵的布局和多普勒接收系统中的一些技术细节。这些技术措施保证了在多普勒图中清晰地显示多径现象和有效地消除小不均匀体的影响。最后还简单地介绍了这个台阵一年来的实测情况。

| Abstract: | In order to investigate the dynamic behaviour of the ionosphere, a three-station array was set up in September, 1985 at Wuhan Ionospheric Observatory, Chinese Academy of Science, Wuhan City, China. It measures continually the Doppler frequency shift of BPM stantard signals transmitted from Shaanxi Astrpnomic Observatory, 5- and 10-MHz during the night, 10- and 15-MHz by day, and measures simultaneously the Faraday rotation of the 136 MHz satellite beacon of ETS-II since being set up. In this paper, some problems which arise in the HE Doppler measurement are discussed in detail. The multipath traces caused by the large scale disturbances are displayed clearly and the influence of scattered signals from the small scale irregularities are eliminated on the Dopplergram displayed by a sonograph as well as by a digital real time display system. Finally, some results of primary observation are also given. |
