Target Motion Effects on Passive Sonar: An Appraisal of Basic Factors.

Abstract

Detection and tracking by passive sonar involves the observation of the target-radiated noise in bearing-cells and time-cells that have their dimensions predetermined by a combination of physical limitations, e.g. the size of the acoustic array, and general factors related to the geometry of the target motion. This present study considers the idealized situation of a plane wavefront being received by a linear array. Conclusions are given relating to the effects of target motion on the allowable observation times for constant speed and heading conditions. Keywords include: Detection, Frequency domain, Monte Carlo technique, Passive sonar, Probability density function, Random encounter, Steady-state case, Target motion, Target-radiated noise, Time domain, and Tracking.
