The diversity of infrared system performance prediction models currently used by different services conflict with the concept of joint operations' where all services must share the common resources to survive. in this respect this study presents an analysis and a comparison of two operational performance models, the U.S. Army's ACQUIRE and the infrared module of the Navy/ Air Force Tactical Decision Aid (TDA), WinEOTDA. Differences in the modeling of underlying physical principles, input parameters, and treatments are analyzed. A comparison of the predicted detection ranges is made using a data set collected in the Gulf of Oman as the meteorological input. Suggestions are sought for the modification of the codes that will lead to the same outputs. Finally the possibility of adopting one of the codes as a standard IDA is analyzed. For the same scenario inputs and with a user-defined sensor model WinEOTDA predicted longer ranges for 100% of the time. WinEOTDA was observed to be more accurate in predicting detection ranges than ACQUIRE because of the improved target modeling

Comparing the Maximum Likelihood Method and a Modified Moment Method to fit a Weibull distribution to aircraft engine failure time data. Güimil, Fernando (Monterey, California. Naval Postgraduate School, 1997-09);This thesis provides a comparison of the accuracies of two methods for fitting a Weibull distribution to a set of aircraft engines time between failure data. One method used is the Maximum Likelihood Method and assumes ...
Elsberry, Russell L. (Monterey, California. Naval Postgraduate School, 1977-03); NPS-63ES77031The coarse-grid version of the tropical cyclone prediction model described by Ley and Elsberry (1976) has been used to evaluate the effect of using operationally- analyzed rather than hand-analyzed data. A series of 41 ...
