The New Method for Calculating Poles of a Scattering Object |
| |
Abstract: | The natural resonances (poles) of a scattering object are important for the target identification. A new method for calculating poles of a scattering object is proposed in this paper. It is shown that the zeros of the Fast Fourier Transform of the integral kernel function are the poles of the scattering object. As an example, the poles of a thin wire conductor are obtained with high precision in very short time by using this method. |
