A Survey of Thermal Radiation from Surface Vessels Part 1

Abstract

Measurements of the operating ranges of a standardized thermal detector and their dependence upon weather conditions were initiated in December 1945 at the Bureau of Ships Test Station, Lewes, Delaware. These measurements are made during the first week in each month and will continue through December 1946. The targets employed are surface traffic passing through Delaware Bay and U.S.S. Callao, a converted German weather ships. The maximum ranges at which these targets can be detected are recorded together with other pertinent data, such as air temperature, absolute humidity and visibility. The total power radiated by the Callao together with the effective radiation density provided by the sky and sea background are also measured. It is hoped to show how and why these factors influence the operating range of a given detector throughout the various seasons of the year.
