Abstract: This study was conducted to· provide a database from which to draw conclusive results on the efficiencies of seismic wave propagation in natural terrain and the resolution and fidelity of multiple frequency signals, and to supplement data for validation of theoretical models of seismic wave propagation. An extensive test program was conducted at White Sands Missile Range, New Mexico, using an electrohydraulic vibrator, an impulse loader, and a vehicle as sources of seismic waves over a 5-m to 1-km range and using explosive seismic sources over a 1- to 10-km range. The results are presented for discrete frequency vibration tests (1-120 Hz), tone burst tests (1-120 Hz), random noise vibration tests, and background noise tests for vehicle, impulse, and explosive tests. Analysis of data has been performed to correlate frequency, amplitude, range, and other signal characteristics with model predictions and to modify model coefficients to produce better predictions for future tests. This study relates the dispersion and attenuation of seismic waves, frequency resolution, and wind and background noise to the refinement of the WES seismic propagation model.
