This thesis is a study in the infrared signature that a ship at sea will emit and how that signal can be used to improve the ability of the marine vehicle to detect and track targets. The need to develop marine infrared systems is established within the context of a brief comparison of the infrared detection scenario to the schemes presently in use. The virtues of exploiting the spectral characteristics of the infrared signature is demonstrated. WHy the spectral system will have an improved range of detection or figure of merit when compared to imaging systems is discussed. Spectral lines and their expected signal strength for typical gas turbine operations are calculated. The types of target information that can be inferred from the spectral detection scenario is addressed. An expected submarine application is presented. Finally, the types of experiments needed to establish the parameters for the development of a full scale engineering model are proposed. ( RH)
