Evaluation of Simple Spherical Spreading Model for Near Vertical Acoustical Propagation
Abstract
A comparison study was performed to evaluate the performance of a simple spherical spreading plus molecular absorption model to a more complex acoustic propagation model for near vertical propagation. The problem of near vertical propagation is important since several acoustic detection systems are being developed for the Army. The operational use of a simple acoustic propagation model in the battlefield will allow for fast computation time providing rapid evaluation of the advantage or disadvantage of using the acoustic detection system. However, simple propagation model, more complex models must be that incorporate many effects of the ground and atmosphere on the propagation of sound. This comparison will determine the limitations.
