Radar cross section （RCS） measurement is significant in the research field of target and environment characteristics. It＇ s an important research method in the field of radar detection, target recognition and electronic warfare. The accurate measurement of the target characteristic data plays an important role in the studies on the scattering mechanism, the establishment of the target and en- vironment scattering model database, and RCS reduction. Based on the theory of electromagnetic si- militude and similitude conditions, the scale model measurement of RCS works at a definite frequen- cy. Comparing with the measurement of real target, scale model measurement has some advantages in technology, conditions, and economy. The theory basis of scale model measurement is introduced firstly. Then the critic technologies of scale model measurement of RCS are summarized. The latest progress and research direction are finally introduced.
