1999 RQ36 Planning
Background
1999 RQ36 was discovered by LINEAR on September 11, 1999. It will approach within
0.033 AU (~13 lunar distances) on September 20.
Goldstone and Arecibo radar observations of this object in September-October 1999
showed that it is about 550 meters in diameter and that it rotates once every
4.3 hours. Spectroscopy by E. Howell (Arecibo Observatory) combined with constraints
on the optical albedo from radar estimates of the diameter showed that this object
is a primitive B-type, one of only a few known among the NEA population. As such,
its surface is very dark at optical wavelengths--approximately as dark as charcoal.
Due to its size and the proximity of its orbit to that of Earth, the Minor
Planet Center has classified 1999 RQ36 as a "Potentially Hazardous Asteroid."
These will be combined Goldstone and Arecibo observations. Goldstone observations
are scheduled on September 12, 18, and 19, and Arecibo observations
are scheduled on September 16, 20, 28, and October 2.
1999 RQ36 will be a strong radar target and we anticipate imaging with a resolution
as fine as 1/8 usec.

Setups
CW Setup
Goldstone and Arecibo observations in 1999 revealed that 1999 RQ36 has a diameter of about
550 meters and a rotation period of about 4.3 hours, so we expect a bandwidth of
about 13 Hz. Let's start with the following CW setup, which will easily resolve the echo
in Doppler frequency:
TX polarization RCP
RCV polarization LCP
Frequencies: 2
Dwell: 20 seconds
Bandwidth: 4000 Hz
Sampling interval: 2500 x 0.1 usec
FFT: 8192 for 0.488-Hz resolution
On subsequent tracks the round-trip time will be less than 40 seconds, so we will
need to switch to a shorter dwell (say, 10 seconds).
