Abstract: An experiment was conducted to test the effectiveness of using a small platform constructed of packed snow to simulate the effects of a snow cover on ground sensors used in vehicle detection and identification. A simple impulsive acoustic source (.45-caliber pistol firing blanks) was used to simplify the interpretation of the experimental measurements. Geophones and microphones on the snow platform and on undisturbed snow nearby were used to record the signals. These measurements show no significant difference between signals recorded on the snow platform and on the surrounding undisturbed snow. Consideration of previous measurements and acoustic theory shows that the platform would have to be much larger in areal extent to affect the recorded signatures; it is the interaction of the acoustic waves with the ground surface over their entire propagation path that controls the properties of the signal at the ground sensor.
