Abstract

The paper deals with the Matrix Pencil method, an efficient numerical method to identify deterministic signals based on either simulation or measurement. The method is usually referred to as a high-resolution technique as it is capable of identifying non-stationary signals, even in the presence of numerical or measurement noise, respectively. The basis functions are complex exponentials with a damping factor. Those functions are rather appropriate to identify electromagnetic waves or distributed currents with an optimal number of elements. The method is applied either in time domain, in frequency domain or in space domain allowing one to identify the original signal by means of a limited number of singular values, poles and residues.
