Advances in ground radar for civil aviation

The need for ground radar for civil aviation is discussed, and also its growth during the last ten years, first in the terminal areas, and more recently to assist control on the airways. Typical radars designed for civil use are next described and possible ways of meeting future requirements. Advances in techniques are then mentioned, and it is shown that the problems of radar data generation and transmission are largely solved. How to make best use of these data in the field of Air Traffic Control is shown to be the subject of active study.
