The calibration problem of a Short Baseline Underwater Vehicle Tracking Range is concerned largely with the coherency of path as the target vehicle passes from the domain of one array into that of another. The arrays are placed approximately in a hexagonal mesh. Thus there are regular locations (triple overlap regions) where the vehicle is tracked simultaneously by three separate arrays. Longbase methods can be used to locate the vehicle in these isolated regions. Presumably the four determinations (three for the individual short baseline arrays and one for the long baseline) can be used to locate the arrays and help calibrate the range. This thesis contains a feasibility study for this idea. Vehicles are placed at known locations in the triple overlap regions. A sequence of correction actions is postulated and the algorithms have been programmed. It appears to work quite well within the confines of this idealized study.
