Ultra-wideband radar target modeling using triangular patch model

To understand the UWB radar system, target scattering performance must be studied. As a widely used model in time domain electromagnetics triangular patch model (TPM) is employed to simulate UWB radar targets. But when the scattered fields are treated, singular points would occur of TPM. The singularity analysis is carried out of TPM and a method is proposed to deal with all kinds of singular points. The method proves effective through an application example.
