Abstract:

Equations are developed to describe centroid tracking, in which the sonar operator tracks a composite signal at a bearing that is a weighted average of the bearings of the torpedo and target submarine. A study is made of the motion of the apparent bearing line and the effects of this motion when corrected-intercept control is exercised and corrections are computed by a recently developed procedure. Acquisition probabilities are computed by suitable modifications to a previously developed simulation model, and compared with the corresponding probabilities obtained when a torpedo maneuver is used to unmask the target.
