Abstract

In calculating poles by theory,the method of moments (MoM) combined with contour integration is a common and smart one.Because of time consuming,it is usually used for the rotationally symmetric objects.In this paper,we approximate the Green’s function by Chebyshev polynomials.So,the factor of frequency can be extracted from electric field integral equation,which will largely decrease computation time in MoM at different frequencies.Then,it is possible to calculate targets’ poles of arbitrary shaped objects.Lastly,by the improved contour integration,three targets’ poles are calculated.

Key words

method of moments / contour integration / radar target poles / Chebyshev approximation
