Abstract :
Part II of a Japanese radar survey continues a report based on a study made by the United States Army which was particularly fruitful because of the obvious willingness of the Japanese to volunteer technical information, in spite of the difficulties of interrogating in a foreign tongue or through an interpreter unfamiliar with technical terminology. Because radar research was carried on separately by the army and navy in Japan, this article complements Part I´s discussion of army radar with a summary of naval developments in the same field, as well as discussing general factors incidental to the manufacture and operation of radar equipment.
