Abstract :
New RCS data on two spheres in rotation are presented. From the simple geometry, the results allow us to verify both the cross-range and down-range distance scales in imaging. With the known RCS of the individual spheres, we find that it is feasible to calibrate the image RCS scale to dBsm, provided care is taken to mitigate the shadowing and sidelobe effects.
