Distributed acoustic sensing (DAS) systems using fiber optic (FO) cables are becoming commonplace in many perimeter security applications. They have the advantage of cost-effectively covering large geographic expanses without temporal or spatial gaps

A curved-grid velocity-stress formulation for viscoelastic wave modeling is used with an arbitrary number of relaxation mechanisms to model a desired [Formula: see text]-behavior. These equations are discretized by high-order staggered finite differe

We introduce a procedure for including the attenuation factor [Formula: see text] in a consistent manner in seismic modeling and show 3D examples. The [Formula: see text] fitting over a chosen frequency band involves two algorithms: The first creates

A simulation study is conducted to demonstrate in principle that time reversal processing can be used to locate sound sources in an outdoor urban area with many buildings. Acoustic pulse propagation in this environment is simulated using a two-dimens

We develop a method for the loading of ground by moving vehicles in large finite-difference time-domain simulations of seismic wave propagation. The objective is to realistically produce two distinct types of ground loading for either wheeled or trac

A finite-difference time-domain (FDTD) method models moving vehicle ground motion in 3D geologic environments, producing results similar to those from actual field experiments. Simulations provide a low-cost alternative to traditional prototype devel
