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.
