Infrared Wake Detection

Abstract

As a part of a program to investigate the detectability of submarine wakes, a dual-channel infrared radiometer built by Barnes Engineering Company is being used for airborne overwater measurements and in submarine model tank experiments. The radiometer employs two thermistor bolometer detectors immersed in germanium lenses at the focus of a Cassegrainian optical system of 12-in focal length and 8-in diameter. Each detector provides an instantaneous field of view of 7 by 33 mrad and a noise-equivalent temperature difference of 0.0016 K.
