Some solar system objects that are candidates for radar imaging are lined by clouds or haze, producing optical imaging tricky or impossible. These atmospheres are transparent to radio frequency waves, and can be imaged using Synthetic Aperture Radar (SAR) which presents its very own penetrating illumination with radio waves.
