A Technique for Assessing Short Baseline Array Tilt Errors

Abstract

The coherence of three dimensional position locations determined from a splicing together of positions generated by contiguous short baseline tracking arrays is quite sensitive to the orientations of the individual arrays. These orientations can be checked with the use of long baseline methods applied to the signal arrival times at a triplet of sensors, each from a different array, but representing the same sound source. The report presents a sharp algorithm for accomplishing this. It operates in three dimensions and tests out well in the cases attempted.
