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.

对极光电离层的数字化研究--电离层探空仪与EISCAT共同设在挪威特罗姆索附近，对极光电离层的测量提供了拟议工作的内容和方向。数据采集和分析是由调查员在Max-Planck Institut Fur Aeronomie工作期间完成的(1983-1989)，随后是英国南极调查局的一家研究咨询公司。现在将撰写的七篇论文将加入已经发表或被接受的四篇论文，这些论文是先前工作的结果。两篇论文提出了一种从高分辨率多普勒和回声定位分析中提取电离层矢量速度的新方法，并将其与EISCAT整体离子速度测量进行了比较。三篇论文涉及在制定数字电离层探空仪数据采集原理方面的新成就。它们表明，在控制电离层回波的信息含量方面，在更好地理解无线电反射、折射、绕射和色散过程的相互作用方面取得了进展。其中一篇论文展示了两种新的电离层探测空间表示方法。有两篇论文涉及极光电离层的自然(焦耳)和人工(无线电)加热。
