Description: This report describes an empirical analysis of a motion model that has been used to generate      random submarine tracks for an antisubmarine warfare tactical decision aid. The model      describes a submarine's motion as a series of transitions between the square cells of a grid that      covers a defined operating region. A 3 x 3 transition matrix is associated with each cell of the      grid which determines the submarine's transitions from a cell. The set of transition matrices      define a Markov process. Despite its discrete nature, this Markov track generating process      has been called a diffusion process in antisubmarine warfare tactical decision aid literature.      The transition matrices are determined by tracks generated by an auxiliary stochastic process      that is presumed to be of higher fidelity but more costly to implement than the Markov      process.
