Abstract
Problems encountered in engineering the interface between a modern data extraction and display system and an existing secondary radar system of earlier design are described. The radar and the ATC building, which are in Iceland, are about 55 km apart. This paper discusses various interference design problems encountered before, during and since the installation and commissioning of the system and the solution found effective for each. The topics discussed include protection of the existing radar system from fault conditions in the new equipment, early difficulties encountered in passing data over the existing telephone circuits, malfunctions caused by harmonic content in the selsyn azimuth data and by departures from specification of the video output of the original radar, and some s.s.r. siting lessons learned from the results obtained.
