Long-Range Artillery Sound Ranging: 'PASS' GR-8 Sound Ranging Data.
Abstract
The GR-8 ground recorder records from the 'PASS' field experiment were reexamined to develop a research data base for use in the evaluation of proposed sound ranging meteorological messages and solution algorithms. Since all surveyed sound sources were located at ranges greater than 10 km, the recorded sound signals are weak due to the atmospheric attenuation. Under these conditions the record reader required automatic aids in selecting the arrival times. Over 500 GR-8 data tapes were semiautomatically read and the automated processes that allowed editing in the selection procedure are defined. Using the current artillery meteorological correction and these automatic aids, this analysis suggests a significant improvement over the manual process of selecting the arrival times. With these aids the record reader was able to provide more timely arrival time data that permitted sound source location with miss-distances less than 1.5% of the over 10 km range targets.
