“…rough analyzing the incident angle variation characteristics for different radome areas, thickness can be accordingly designed to compensate the adverse effect of incident angle. Average incident angle with proper modification is effective in efficiently designing the thickness profile through the half-wave thickness expression [12]. Smooth thickness profile is guaranteed by the continuous radome shape which results in the gradual variation of average incident angle.…”

“…Essentially, the half-wave thickness implies optimal transmission efficiency and gives little consideration to BSE characteristics. In this work, on the basis of the thickness profile obtained by the average incident angle method in [12], radome IPD under scan angles with large BSE is corrected for symmetry w.r.t. the antenna axis, thus improving the BSE characteristics.…”

Variable thickness design is capable of yielding excellent electromagnetic (EM) performance for streamlined airborne radomes. The traditional optimization method using evolutionary computation (EC) techniques can yield variable thickness radome (VTR) design with optimal EM performance but uncontrollable thickness profile, leading to manufacturing difficulties. Thickness profile design based on average incident angle is an efficient way for VTR design with smooth thickness profile, whereas the boresight error (BSE) is relatively large. In this work, insertion phase delay (IPD) correction is introduced in the efficient thickness profile design process to realize a better balance between EM performance and thickness profile smoothness of airborne radomes. The thickness profile obtained from average incident angle is adjusted for IPD distribution symmetry with respect to the antenna axis under scan angles with large BSE. Results indicate that the proposed method can effectively improve the BSE characteristics at the expense of slight deterioration of computational efficiency and thickness profile smoothness.
