Abstract
This paper describes a procedure, analogous to Prony's method, for extracting the complex-frequency poles of electromagnetic transfer functions. The method is refined mathematically and is applied to both electrical and mechanical test cases. The paper explains a multiple processing technique, involving the overlaying of several pole sets, by which redundant data are used to separate actual from curve-fitting poles. Identification of an unknown target by comparing its scattered field with the poles sets of known targets is also illustrated for simple targets.Keywords
