Abstract :
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.
