Singularity Extraction of EMP Response Waveforms by Prony's Method.
Abstract
The Singularity Expansion Method has grown from a theoretical idea to a numerical technique that calculates the poles of a given scattering object. It has spawned the study and growth of Prony's method, which calculates the poles of the scattering object, from the scatter field that is in response to an incident electromagnetic wave. Here is presented the results of an attempt to use Prony's method on EMP response waveforms on ships. The technique to acquire the experimental data is detailed; the numerical problem is posed, and the goals are quickly simplified to attempting to find the best curve-fit to the waveform, using complex exponentials, and then hoping to eliminate the curve-fit poles. A method is presented that aids in the 'physical pole' selection process, and explained also is the significance of the right half plane poles in the results. (Author)
