We present a calculation program in this paper, based on the physical optical theory ( po ) theary to predict bse and bses for a conical type of radome. the po theory is used to determine the ficticius currents electrical and magnetic on the inner face of the radome, which is illuminated directly by the radar antenna, and then use the transmission matrix mothod to determine the outer surface ficticion currents, the radiated from the antenna through radome is considered as the radiation field of these ficticion current
本文提出了一種基於物理光學理論預測正圓錐天線罩瞄準誤差及瞄準誤差斜率的計算程序。首先，雷達天線照射到天線罩內壁，應用物理光學法求出內壁等效的電流和磁流，其次，根據傳輸矩陣理論求出外壁等效電流和磁流，天線通過天線罩的遠區場即可認為是外壁等效電、磁流產生的場。 -
