Accurate Bi-static RCS Measurement for scaled Target using Noise Illuminated W-band Radiometer

This paper is proposed the new type of RCS measuring method and system for scaled objects. Unlike any other conventional radar-based RCS measuring system, the proposed method uses W-band radiometer receiver with noise illumination and X-Y scanner which is compact and easy operation in samll size room. The measured RCS accuracy for reference metal object of rectangular plate, cylinder and sphere is smaller than 1.0 dB in the azimuth scan angle of +/- 5 degrees
