• In this paper, we proposed a fast and accurately calculated method to estimate the deviation of wideband angular glint based on single frequency or narrow band modeling method of the angular glint. By analyzing the three existing methods of modeling the target angular glint, we show that such methods are consistent when the geometrical optics approximation and linear polarized receiving antenna are assumed. Considering of the tracking system by wideband monopulse radar, the fast calculated method we present can estimate the angular glint in each resolution unit using modeling method of single frequency which is the center one of the whole bandwidth. The mathematical analysis of the unity between the wideband and narrowband modeling method is demonstrated, and the correctness of the new calculated method is well validated by high-frequency electromagnetic simulations based on the physical optics.
