Abstract

In March 2005, Planning Systems, Inc. (PSI), Advanced Acoustic Concepts (AAC) and the U.S. Army Research Development and Engineering Center (ARDEC) tested the PSI Acoustic Counter Battery System (ACBS) at the Yuma Proving Ground (YPG). ACBS was designed to acoustically detect and locate mortar fire, and to detect and locate heavy artillery fire out to ranges beyond 12 km. During analysis of the test data, we discovered that long-range sensors were receiving multiple pulses in doublets and triplets from a single shot. Additionally, we observed that the leading pulses were arriving earlier than anticipated by surface speed of sound calculations. The analysis team modeled the atmosphere recorded during the test and identified the possible causes of multiple arrivals by modeling the supersonic projectile trajectory and by using Green's Function Parabolic Equation numerical techniques to propagate recorded pulses from the source to receivers. The lessons learned will be applied to adjust the signal processing algorithms in the ACBS. This paper describes the test setup and reports the results of the analysis.
