Model measurement of radar cross-section for fully coated target by variance in the size

Using dimensional analysis, geometric and physical optic approximation, a new method is suggested for electromagnetic scattering measurement of a lossy target. By this method, model measurement for radar cross-section (RCS) can be carried out at the same frequency with a prototype by variance in the size of model. This is significant for the lack of experimental equipment required or the problem of frequency dependency of radar absorbing materials on the objects. For the purpose of verification, the measurements of a cylinder are carried out at X band by means of a transition model. The computed results from models agree well with the measured data by the prototype itself.
