Abstract

Microwave diversity imaging is used to study diaphanization by absorber covering. In this imaging system the absorber-covered object is illuminated by a plane wave and the backscattered field is received at a set of frequencies. The object is then rotated and the measurement is repeated. The authors study the diaphanization by comparing the mean radar cross-section, the range profile (defined as the Fourier transform of the backscattered field), the sinogram (a two-dimensional intensity varied display with an abscissa of differential range, an ordinate of aspect angle, and intensity or brightness proportional to the magnitude of the range profile), and the reconstructed image before and after absorber covering.<>
