Monitoring the Calibration of a Torpedo Test Range

Abstract

Post test analysis of vehicle tracking data taken from a three dimensional underwater range requires the splicing together of several pieces of track individually produced by distinct transducer arrays. The locations and orientations of the arrays must be known precisely in order to convert locally determined tracks into a coherent record in the general range coordinate system. The maintenance of calibration of the system is a problem and this study presents some least squares methodology that uses the tracking data itself to monitor it. More specifically, methodologies are developed to improve upon the array displacement and orientation correction algorithms and to estimate timing synchronization offsets. Applications are made to real data.
