Abstract

The vacuum of space presents special problems for optical image sensors. Metallic objects in this environment can produce intense specular reflections and deep shadows. By combining the polarized RCS with an incomplete camera image, we have been able to better determine the shape of some simple 3D objects. The radar data is used in an iterative procedure that generates successive approxima-tions to the target shape by minimizing the error between computed scattering cross-sections and the observed radar returns. Favorable results have been obtained for simulations and experiments recon-structing plates, ellipsoids and arbitrary surfaces.
