An Overview of Stochastic Signal Modeling.
Abstract
Knowing the average value of a fluctuating acoustics field is not enough to provide criteria for the design of sonar systems. More important are the statistics that measure the decorrelations of the field and its intensity. After discussing the variabilities of the environment that affect the field, this report summarizes the four major approaches to these problems: deterministic, phenomenological, Monte Carlo, and stochastic modeling. Two different courses of action are recommended for computing the desired statistics. In the first course, existing models, each dealing with some effects and ignoring others, can be linked to handle the simplest problems. In the second course, a Monte Carlo approach is recommended for more difficult problems, although its generality is gained at the expense of intensive computer usage. (Author).
