Abstract

In this paper we examine the famous unpublished memorandum of 1935 in which R. A. Watson-Watt proposed the principles of radar. Starting from the numerical results he quoted, we show how he arrived at his conclusions using nothing more than simple calculations. The origins of an important modern technology are to be found in a combination of prescience and fundamental engineering skills.
