Complex radar cross-section measurements were made at ten harmonically-related frequencies on a set of target models resembling space objects. The frequencies used 1.08, 2.16, 3.24 ... 10.8 GHz lay in the resonance region of the target scattering characteristics. By Fourier synthesis, the approximate ramp response of these targets can be constructed. The behavior of these ramp response waveforms vs. radar look angle and interrogating signal polarization is discussed. An interactive target imaging process was developed to use ramp response data at three orthogonal look angles. Techniques for image generation using short pulse radar data and three or five resonance region harmonics were investigated. Images are presented for some of the targets using measured short pulse and harmonic data. Modified author abstract
