Abstract: It is now possible to model elongated elastic targets via the Waterman methodology of the extended boundary condition equations. Due to rapid advances in computers it is now possible to perform numerical calculations of the scattered field in any direction as a function of frequency. We take advantage of this capability to study pulse signals from such targets in which we vary shell material, shell thickness, and elongation of the target. The pulse signals are then reconstructed via Fourier transform methods and the results analyzed and interpreted. !3
