| 摘 要： | 本文导出了任意旋转反射器天线在任意双站角的散射场和雷达截面(RCS),其中反射场由几何光学法(GO)求得,绕射场则利用基于物理绕射理论(PTD)与等效线电流辐射积分公式导出的等效电磁流法求得。分别计算了轴向入射和偏轴向入射时在任意散射方向上水平极化与垂直极化两种情况下的双站RCS,并给出了这些结果的立体图形式。方法简化为单站情况时的计算结果与实验值大致相符。

| Abstract: | The scattered field and radar cross section (RCS) of arbitrarily rotary reflectors for arbitrary aspects of bistation are investigated, where the reflected field is obtained by Geometrical Optics, and the diffracted field is computed by the method of equi valent currents (MEC) based on the derivation of an asymptotic relationship between the surface radiation integral of the physical theory of diffraction and the line radiation integral of MEC. The RCS pattern for both axial and paraxial incidences with horizontal and vertical polarizations are calculated respectively. The results obtained are expressed by solid figures. The simplified results of monostatic RCS from the method in this paper agree well with the experimental results. |
