“…(18) and Eq. (19), it is easy to find that they are identical. It means that in the full wave or the high-frequency simulation, the calculation of wideband angular glint can be replaced by the single frequency simulation which has the much less calculated time especially for the extremely complex target and without the IFFT operation, the proposed fast calculated method has low mathematical complexity compared with the wideband method.…”

“…And also the twodimensional image of the target can be reconstructed due to the Range-Doppler (RD) technology [17] based on the Synthetic Aperture Radar (SAR) system, and also the threedimensional microwave image can be reconstructed based on the multi-view radar system [18]. The modeling method and the viewpoint of the target angular glint under the wideband system can also be extended due to appearance of HRRP, and the corresponding calculation for complex target which is composed multi-scattering centers had been presented [19].…”

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.

“…Resolution enhancement is an effective way to suppress angular glint errors [6–8]; however, numerical results show that angular errors cannot be completely eliminated due to the influence of the aspect dependencies of the attributed SCs. Aspect dependencies mean that the scattering amplitude and location of an SC are dependent closely on the aspect angle of radar line of sight (LOS).…”
