Abstract. This paper highlights the important role
played by the EISCAT radar for verification in the development of tomographic
techniques to produce images of ionospheric electron density. A brief review is
given of some of the stages in the application of tomographic reconstruction
techniques to the ionosphere. Results are presented to illustrate the
effectiveness of the method in imaging ionospheric structures at high latitudes.
In addition, the results include the first tomographic image of the ionosphere
for a region extending from mid-latitudes over mainland Scandinavia to high
latitudes above Svalbard.
