S-band radar mapping of Saturn's rings.

We propose to continue radar imaging of Saturn's rings using the S-band solar system radar as the opening angle of the rings, B , decreases to 8 in February 2008, lower than any elevation we have previously observed. These observations are needed to test the theoretical prediction that the strong azimuthal asymmetry we have observed in the A ring will reach a maximum amplitude when B 12 . We will also continue to characterize the unexpectedly steep decline in normalized radar cross-section with increasing elevation angle observed in 1999 ­ 2007. In 2008 we are also requesting simultaneous observations at the GBT, which will both double the overall SNR achievable as Saturn moves south and provide a robust backup option in the event of recoverable transmitter problems at Arecibo.
