Understanding and improving acoustic to seismic coupling as it pertains to Sandia's helicopter detector
Abstract
The basic physics of the acoustic-to-seismic coupling phenomenon involved in the operation of a helicopter detector under development are reported. A series of tests were conducted near Albuquerque, New Mexico, investigating the coupling phenomenon using an impulsive noise source and two different helicopters. Results of the tests including the evaluation of a new microphone windscreen design are presented.
