Target motion effects on passive sonar: an appraisal of basic factors
Abstract
Detection and tracking by passive sonar involve 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.
