Seismic Localization of Hostile Artillery.

Abstract

This report comprises the final statement regarding some initial exploratory research done by the Institute for Acoustical Research (IAR) on the Hostile Artillery Location (HAL) project. The objective of this research was to re-examine experimental data collected by Honeywell, Inc. and the Environmental Research Institute of Michigan (ERIM) during December 1975. The data collected comprised a series of digital tapes recording the response of a seismometer array to the firing of various howitzers at various ranges. IAR's analysis of this data, though not considered technically complete, nevertheless is considered very successful at least with respect to bearing estimates at 5 km. The composite IAr estimate on three firings is within a few hundredths degree of true and the standard deviation is 1 1/2 degrees. Range estimates can be improved with a larger array and a more sophisticated second stage. (Author)
