摘要
三面角反射体是一种重要的无源对抗器材,高效、准确、快速地预估其雷达散射截面积(Radar Cross Section,RCS)具有重要意义。以方形三面角反射体为例,推导了利用改进的几何光学/区域投影法(Geometrical Optics/Area Projection,GO/AP)进行RCS预估的一般流程;基于该流程对方形、圆形三面角反射体的单站RCS进行预估,将预估结果与RCS最大值的经验公式以及FEKO软件的仿真结果进行对比,表明改进的GO/AP法具有正确性、快速性和广泛适应性;针对异型三面角反射体,提出一种基于GO/AP算法利用SolidWorks软件进行RCS快速预估的方法。
The trihedral corner reflector is an important kind of passive countermeasure equipment, so it is quite significant to evaluate its radar cross section（RCS） efficiently and accurately. Taking the square tri- hedral corner reflector as an example, the general process of RCS estimation using GO/AP method is de- duced, and the GO/AP method at boundary angles of incidence is improved. Then the RCS of square corner reflector and circular corner reflector are estimated by the improvedGO/AP method. Comparison with FE- KO simulation results as well as empirical formula of maximum value shows the validity and adaptability of the improved GO/AP method. Also, a fast RCS estimation method for all kinds of trihedral corner reflectors is proposed by combining the GO/AP method with the SolidWorks software.
