Radar Imaging of Six Near-Earth Asteroids During April-September 2009

We propose to use the Arecibo S-band radar to carry out Doppler-only spectroscopy and delay-Doppler imaging of six near-Earth asteroids (NEAs) during April-September 2009. Two of these targets, (136617) 1994 CC and 2001 FE90, represent outstanding opportunities with peak signal-to-noise ratios of thousands per transmit/receive cycle. The other four NEAs, 2008 SV11, (163697) 2003 EF54, 2005 CW25, and 2000 CO101, are weaker but still have the potential to yield high-resolution 3-D shape models. Given detection statistics to date, it is likely that at least one target will be a binary or contact binary system. It is also fairly likely that at least one high-polarization-ratio target will be observed, enabling us to test the recent finding that such ob jects usually belong to the E or V taxonomic classes.
