| 摘 要： | 几何光学/区域投影(Geometrical Optics/Area Projection, GO/AP)法是一种综合利用GO和AP进行电大尺寸目标单站雷达散射截面积(Radar Cross Section, RCS)预估的高频混合算法.文章推导建立了利用GO/AP法进行RCS预估的通用流程, 计算出不同入射方向下三角形三面角反射RCS的完整表达式; 将其与RCS最大值的经验公式以及FEKO软件的仿真结果进行对比, 验证了GO/AP法的可行性; 在边界入射方向对GO/AP算法进行改进, 进一步拓宽了GO/AP法对观察角的适应范围.

| Abstract: | Geometrical optics/area projection(GO/AP) is a hybrid high-frequency method, which can estimate the corner reflector monostatic radar cross section(RCS). The general process of RCS estimation using GO/AP method is proposed, and the complete RCS analytic expressions of triangular trihedral corner reflectors are derived, which are compared with FEKO simulation results as well as empirical formula of maximum value, and the validity of GO/AP method is confirmed. The GO/AP method is improved at boundary angles of incidence further broadening the adaptive range of the GO/AP method. |
