TL;DR: The radar echos at 12.6 cm showed that the particles of the rings of Saturn are very efficient radar reflectors with diameters on the order of a meter or larger.

TL;DR: In this article, the Goldstone radar system was used to scan the Martian surface for three complete rotations, each at different latitudes, and large-scale variations in altitude cover a range of 14 km.

TL;DR: In this paper, radar and optical data are combined to suggest an irregular rocky surface slightly smoothed by a mantle of loose material, which is similar to the one in this paper.
Abstract: Radar observations of Toro were made with a (one-dimensional) resolution of 0.005 arc sec. When radar and optical data are combined, they suggest an irregular rocky surface slightly smoothed by a mantle of loose material.

TL;DR: In this paper, the disappearance of virtually all structure in the fringe-amplitude pattern for the August data is consistent with the occurence of an explosive outburst of radio radiation interferometer on 1972 November 7 disclosing an additional increase in correlated flux with a reappearance of structure.
Abstract: io frequency of 7850 MHz three-fold between 1972 June 6 and August 29. The disappearance of virtually all structure in the fringe-amplitude pattern for the August data is consistent with the occurence of an explosive outburst of radio radiation interferometer on 1972 November 7 disclose an additional increase in correlated flux with a reappearance of structure in the fringe-amplitude curve. These findings are consistent with a single, spherically symmetric source expanding with an apparent velocity several times the speed of light. The assumption that mulitple, independent outbursts occurred during this period avoids the implication of relativistic expansion.
