摘要

通过实验研究，对二面体角反射镜的后向散射特性进行了研究。讨论了频率特性和方位特性。另一方面，验证了雷达吸波材料(RAM)的影响。在此基础上，设计并制造了一个物理尺寸约为7.1 m高、3 m宽的紧凑范围平面扫描框架(PSF)系统。其雷达截面(RCS)的估计采用一维(1-D)下程成像方法。1- d图像证明其RCS小于0 dBsm (1 m/sup /)。该方法很好地满足了实际工程的要求，并已成功地应用于大型CR性能测试中。

Stealthy design of a compact range plane scanning frame

Through experimental study, backscatter characteristics of dihedral corner reflectors are studied. Both frequency and azimuth characteristics are discussed. On the other hand, effect of radar absorbing material (RAM) is verified. Based on all these experiments, a compact range (CR) plane scanning frame (PSF) system, which physical size is about 7.1 m high and 3 m wide, is designed and manufactured. The estimation of its radar cross section (RCS) is by one-dimensional (1-D) down-range imaging method. 1-D images prove that its RCS is less than 0 dBsm (1 m/sup 2/. It meets requirements of practical engineering very well and has been applied in a large CR performance testing successfully.
