Proposal Title: Systematic Radar Observations of Small Near­Earth Asteroids
ABSTRACT:
We propose a systematic radar survey of all available NEAs in an 8­hour observing run one night each month.
Objects are available at any given time, but newly discovered objects will be more plentiful near the time of new
moon. We expect to observe about 8­10 objects each month to measure orbit distance and velocity, object size,
spin rate, polarization ratio and radar reflectance properties. These characteristics will give new insights about
smaller NEAs than previously sampled.
