摘要
用物理光学法计算了布撒器的雷达截面,并与外场测量结果进行了比较。计算的RCS～θ曲线与测量的RCS～θ曲线变化趋势相同,在典型方向上的计算结果与测量结果比较吻合。表明镜面回波在强度上占绝对优势的目标RCS计算中,物理光学法可以给出工程上可用的结果。
The radar cross sections of dispenser are computed by using the Physical Optics Method, and the computed results are compared with the measured results. The varying tendency of computed RCS～θ curves is the same of the measured RCS～θ curves, and the computed results are in agreement with the measured results in typical direction. In RCS computation where mirror echo occupies absolute predominance, the research results show that Physical Optics Method can give usable results for engineering design.
