摘　　要：为实现浮空式角反射器RCS快速预估,通过改进基于几何光学和区域投影的高频混合算法,推导出双棱锥型角反射器的全向RCS表达式;通过分析平面波在双棱锥型角反射器内表面的反射情况,推导建立了双棱锥型角反射器全极化RCS的快速预估流程;将RCS快速预估方法计算结果与弹跳射线法仿真结果进行了对比,证明了全极化RCS快速预估的可行性,为进一步实现浮空式角反射器阵列的快速RCS预估以及快速布放决策提供了重要帮助。To realize the fast RCS estimation of the air-floating corner reflector,the omni-directional RCS expression of the bipyramid corner reflector is calculated by improving the high-frequency hybrid method based on geometrical optics and area projection;By analyzing the reflection of plane wave on the inner surface of bipyramid corner reflector,the full-polarized RCS fast estimation process of it is established.The calculation results of the fast RCS estimation method are compared with the simulation results of shooting-and-bouncing-ray method,which proves the feasibility of the full-polarized RCS fast estimation.This method provides an important help for the fast RCS estimation and fast deployment decision of the air-floating corner reflector array.
