Research Publications from a Digital Ionosonde

利用与挪威特罗姆瑟附近的EISCAT共同部署的数字研究电离层仪对极光电离层进行测量，提供了拟议工作的内容和方向。数据采集和分析（1983-1989年）由研究员在马克斯-普朗克航空研究所工作期间完成，随后由英国南极调查局的研究顾问完成。现在将要撰写的七篇论文将加入四篇已经发表或被接受的论文，这些论文都是以前工作的结果。两篇论文提出了一种利用高分辨率多普勒和回波定位分析获得电离层矢量速度的新方法，并将其与EISCAT体离子速度测量结果进行了比较。三篇论文讨论了数字电离层探空仪数据采集原理发展的新成果。它们表明在更好地理解无线电反射、折射、衍射和色散过程在控制电离层探空仪回波信息内容方面的相互作用方面取得了进展。一篇论文展示了两种电离层探测空间表示的新方法。两篇论文是关于自然（焦耳）和人工（无线电）加热极光电离层的。

Measurements of the auroral ionosphere using a digital research-ionosonde co-located with EISCAT near Tromso Norway provide the content and orientation of the proposed work. Data acquisition and analysis were accomplished (1983-1989) by the investigator during a stipendium with the Max-Planck Institut fur Aeronomie, followed by a research consultancy at the British Antarctic Survey. The seven papers now to be written will join four already published, or accepted, which have resulted from prior work. Two papers present a new method for deriving ionospheric vector velocities from high resolution Doppler and echolocation analyses and undertaking their comparison with EISCAT bulk ion- velocity measurements. Three papers are concerned with new achievements in the development of data acquisition principles for digital ionosondes. They show progress toward a better understanding of the interplay of the processes of radio reflection, refraction, diffraction and dispersion in controlling the information content of ionosonde echoes. One paper demonstrates two new methods for the spatial representation of ionospheric soundings. Two papers are concerned with natural (Joule) and artificial (radio) heating of the auroral ionosphere.
