摘要
根据物理光学方法(PO)和半空间并矢格林函数,推导出半空间中理想导体的散射场。根据该散射场,首次推导出半空间中理想导体目标的缩比关系,并具体给出了半空间中典型理想导体目标(薄平板和柱面)的RCS缩比因子表示式。为了验证该公式的正确性,矩量法仿真同时给出了直接计算原型目标和通过该缩比因子和缩比模型所得原型目标的RCS。数值结果表明,该缩比关系是有效的。
The scattering fields of a perfect conducting object are evaluated by the physical optics （PO） and half space dyadic Green＇s function. Then the scaling relationship of a perfect conducting object in half-space is proposed in this paper. According to the scaling relationship, the scaling factors of the plate and cylinder in half space are presented. To verify the validity of the formulas, the radar cross seetion （RCS） of the original target and the scaling model target with the scaling factor is computed with the moment method （MOM）. Numerical results show that the formulas are feasible.
