File 81/24 Scientific Programming of the EISCAT Digital Correlator (Revised)
This report describes the basic philosophy of how to create special-purpose microprograms for the EISCAT digital correlator. By Terance Ho and Hans-Jørgen Alger
File 80/23 EISCAT Data Gathering and Dissemination
By Alan Farmer
File 80/22 EISCAT Experiment Preparation Manual
This manual is intended as a guide for the preparation of experiments to be run on the EISCAT radar. It documents software availability to run EISCAT experiments together with sufficient details about the EISCAT hardware to understand the software descriptions. By Joseph Armstrong
File 80/21 EISCAT VHF Antenna Tests
The report contains the main results of the measurements on the EISCAT VHF antenna during the RF acceptance tests in December 1979 and March 1980. By Per-Simon Kildal
File 80/20 Correlator Buffer-Memory for the EISCAT Radar System
Correlator buffer-memory is a device which is going to be used as input data-area for the EISCAT digital correlator. It consist of two memory data-parts which can be addressed simultaneously. So, the loading of data to the buffer-memory and reading to the correlator are total independent of each other. The buffer-memory has 8 program-counters which are programable from the computer. These counters are used for addressing while writing data from the filter and into the buffer. By Svein a. Kvalvik
File 79/19 Lectures for EISCAT Personnel - Volume I
Very popular early introduction to many things related to the ionosphere and incoherent scatter By Kristen Folkestad (EISCAT's first Technical Director)

File 78/6 Discrete Phase Steering by Permuting Precut Phase Cables
The note describes a method to phase steer a linear array antenna to a discrete number of direction by rearranging the sequence of phase cables that are connected to each array element. The phase cables must be precut to specific lengths that are evaluated. By Per-Simon Kildal
File 78/5 Measurement Principles in the EISCAT System
This report reproduces the contents of the three first chapters of ""A Design Study of a Multibit, Digital Correlator for the EISCAT radar System"", A thesis by Hans-Jørgen Alker, November 1976.
File 78/4 The Bandwidth of a Linear Phased Array with Stepped Delay Corrections
The note discusses the bandwidth limitation which gradually developes as the beam is phased away from that beam direction which corresponds to the correct group delays. A scheme for the increase in antenna bandwidth by introducing group delay corrections in steps along the antenna aperture is then discussed and relations between the number of groups required for various bandwidths are developed. By T. Hagfors
File 78/3 The Effect of Ice on an Antenna Reflector
By T. Hagfors
File 78/2 Least Mean Square Fitting of Data to Physical Models
The note describes a general least mean square fitting procedure for adjusting parameters in a physical model to make the model predictious best fit the result of an observation. The method should find application to such EISCAT problems as the fitting of the theoretical spectra (or correlation functions) to the corresponding observations or to the deduction of antenna pointing deficiencies from radio astronomy observations. By T. Hagfors
File 77/1 Balance Between Investment in Reflector and Feed in the VHF Cylindrical Antenna
The note describes a method for evaluating the cost of the feeder system in such a way that the feed-investment is as cost effective as the investment in the mechanical structure. By P.S Kildal and T. Hagfors
