Abstract
THE story of the development of radar during the War is now well known-how it started as a defensive measure to give warning of the approach of enemy aircraft to the coasts of Britain, and grew finally to take an important offensive role in almost every form of warfare. An outline of the history of this remarkable development has been given in Nature by Sir Robert Watson-Watt*. One of the fields in which radar technique has made very large contributions is that of air navigation. In war-time, aircraft must fly in all kinds of weather, by day and by night, and the development of radio aids to replace those visual aids available in clear weather was of paramount importance. In peace-time it is just as important that aircraft should be able to fly with safety in all kinds of weather if aviation is to give regular and reliable passenger and freight service. It is still true, however, that the weather is the main limitation on flying, and although much has been accomplished, much remains to be done.
