“…In recent years, there exists an increasing concern about the BSE problem of ARS. Many methods including geometrical optics (GO) [4], ray tracing (RT) [5,6], method of moments (MoM), multilevel fast multipole algorithm (MLMFA) [7,8] and some hybrid methods [9,10] have been employed to analyze the ARS problems. However, GO-and RT-related methods are not accurate enough especially for inhomogeneous radomes, while the common MLFMA accelerated MoM are not efficient for problems with changing permittivity and shape.…”

“…When the array antenna is mounted on electrically large platforms, its pattern will be disturbed. When using the UTD method to analyze the disturbed radiation of the array antenna, hybrid methods are usually required [5][6][7][8][9] since UTD cannot deal with calculation of current distribution on complex antennas. These hybrid methods possess good precision in calculation; however, iterative procedures are always needed to modify matrix equations, which will lead to great increase in computational resource demand and rapid decrease in computational efficiency as the electrical size of antenna and platform increases.…”
