Understanding and improving acoustic to seismic coupling as it pertains to Sandia's helicopter detector
Technical Report
·
OSTI ID:5733564
This report covers results to date of an ongoing study undertaken in mid 1984 for the purpose of understanding the basic physics of the acoustic-to-seismic coupling phenomenon involved in the operation of a helicopter detector under development at Sandia National Laboratories. This study has been recently expanded to include assistance from the US Army Waterways Experiment Station and the University of Mississippi. A series of tests were conducted near Albuquerque, New Mexico USA, for the purpose of investigating the coupling phenomenon using an impulsive noise source and two different helicopters. Results of these tests including the evaluation of a new microphone windscreen design are reported.
