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.
