A review of research indicates that the attenuation of seismic impulses is a complex function of such factors as moisture, soil thickness, substrata homogeneity, substrata consistency, and vegetation. The problem encountered when seismic devices are employed in a tactical situation is the prediction of ranges of detection for different soil types without resorting to soil samples, compression tests, etc. A knowledge of the seismic characteristics or the ranges of detection in various soil types would be very beneficial when employing seismic devices. This thesis will show a relationship, useful for prediction, between the attenuation properties and the range at which a test signal is first detected at a preset level.
