By means of dimensional analysis, geometric, and physical optic approximation, a new method is suggested for the electromagnetic scattering measurement of a fully coated lossy target. Using this method, a model measurement for the radar cross section (RCS) can be carried out at the same frequency with a prototype by varying the size of model. This is significant in 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 and plate are carried out at X‐band by means of a transition model. The computed results from models agree well with the measured data in the prototype itself. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 19: 57–59, 1998.
