On the Theory of Passive Acoustic Detection.
Abstract
We present a critical review of the fundamental ideas that underlie the conventional theory of acoustic detection. This review is constructed around the suggestion that acoustic detection apparatus be employed for collecting information about a complete set of tactically relevant parameters rather than for testing hypothesis. This idea is illustrated by applying the Woodward and Davies concept of sample-path information to the problem of detection of signals in white noise. Finally, we argue that within such an information-theoretic framework, information generally disregarded by conventional procedures can be extracted from the received voltage history. To obtain this additional amount of information, it is required that we possess a far more detailed description of underwater acoustics than what a conventional theory would demand. In return, however, passive range measurements based on the received voltage history alone become conceptually feasible. (Author)
