Radar Observations of Asteroid 7822 (1991 CS)

We report Doppler-only (cw) radar observations of 1991 CS obtained at Goldstone at a transmitter frequency of 8510 MHz (3.5 cm) on 1996 August 26, 27, 28, and 29.

Radar Investigations of Earth-Approaching Asteroids

Much useful information about physical and dynamical properties can be obtained from radar observations of near-Earth asteroids that come within reach of the Arecibo and Goldstone telescopes.

Radar Investigations of Asteroids

Resolution of an asteroid's echoes in Doppler frequency and/or time delay provides 1-D or 2-D images, and hence direct measurements of the asteroid's size and shape even though its angular extent is tiny compared to that of the radar beam.

Radar Observations of Io

Radar measurements of Io can provide unique constraints on near-surface bulk density and roughness at cm-to-km scales.
