Abstract:

For vehicle designers, the main goal of experiments on the observability of combat vehicles is a comparison of the probability of detection for two vehicles as a function of range. This paper addresses the statistical techniques to analyze such data to compare the probability of detection of the two vehicles as a function of range. Two techniques are compared 1. Fitting logistic curves to the data of the vehicles, and 2. Using the Fisher Exact Test to compare the probability of detection of the two vehicles at each range. The paper discusses the issues of background variability and confidence levels for hypothesis testing. Finally, a recommendation is made on how to write a specification for the detectability of a vehicle.
