A Concept for Efficient Signal Excess Calculation for Multistatic Operations Analysis

Abstract

This paper presents a method for reducing the time required to calculate signal excess for multistatic sonar systems in support of operations analysis. Runtime can be improved by a factor of 10 to 50 by reusing modeled components that go into the signal excess equation. The presented method introduces errors into the acoustic calculation that, when managed by the analyst, will have negligible effect on the operations analysis result.
