Effects of Uniform Target Density on Random Search

Abstract

This thesis was motivated by a study performed by Commander Submarine Force Pacific (COMSUBPAC) of detection rates for a random search model. COMSUBPAC's study concluded that the probability of nondetection to time t, PND (t), was not of the form exp (gamma t), as believed by many. The target motion model used for that study was a new and interesting model, therefore this investigation began by analyzing that model. This investigation discovered that the density of targets for COMSUBPAC's motion model was not uniform over the search area, which might lead to a nonexponential form for PND (t). To lend support to the hypothesis that a uniform distribution of target position can lead to an exponential from of PND (t) the target motion was altered to achieve a uniform target density. The same basic target motion was used because of its inherent advantages over other target motion models.
