Binary Asteroids in the Near-Earth Object Population
TLDR
This system and other binary near-Earth asteroids have spheroidal primaries spinning near the breakup point for strengthless bodies, suggesting that the binaries formed by spin-up and fission, probably as a result of tidal disruption during close planetary encounters, may be binary systems.

Mainbelt Asteroids: Results of Arecibo and Goldstone Radar Observations of 37 Objects during 1980-1995
Abstract We report detailed results of Arecibo and Goldstone radar observations of 30 mainbelt asteroids (MBAs) during 1980–1995. In addition to estimates of radar cross section, radar albedo, and…

Topography of the lunar poles from radar interferometry: a survey of cold trap locations.
TLDR
Detailed topographic maps of the lunar poles have been obtained by Earth-based radar interferometry with the 3.5-centimeter wavelength Goldstone Solar System Radar using digital elevation models to locate regions that are in permanent shadow from solar illumination and may harbor ice deposits.

Arecibo Radar Mapping of the Lunar Poles: A Search for Ice Deposits
The Arecibo 12.6-centimeter wavelength radar system was used to image the polar regions of the moon at a resolution of 125 meters in a search for ice deposits in areas of possible permanent shadow…

Icy Galilean Satellites: Modeling Radar Reflectivities as a Coherent Backscatter Effect
Abstract The icy moons of Jupiter, Europa, Ganymede, and Callisto, are efficient backscatterers of centimeter-wavelength radiation. At 3.5-cm and 13-cm wavelengths their specific radar cross sections…

No evidence for thick deposits of ice at the lunar south pole
TLDR
New 20-m resolution, 13-cm-wavelength radar images are presented that show no evidence for concentrated deposits of water ice in Shackleton crater or elsewhere at the Moon's south pole, consistent with the ice being present only as disseminated grains in the lunar regolith.

Analysis of volcanic surface morphology on Venus from comparison of Arecibo, Magellan, and terrestrial airborne radar data
Arecibo Observatory and Magellan radar data for Venus are compared to airborne radar images for potential terrestrial analog surfaces. Volcanic deposits in Western Eistla Regio and northern Sedna…

Digital elevation models of the Moon from Earth-based radar interferometry
TLDR
The theoretical background, experimental setup, and processing techniques for a sequence of observations performed with the Goldstone Solar System Radar in 1997 are described, providing radar imagery and digital elevation models of the polar areas and other small regions at /spl sim/100 m spatial and /spl Sim/50 m height resolutions.
