The histories of individual asteroids, and particularly near-Earth 
objects, reflect continuous interaction among their shapes, 
rotation states, and orbits due to the effects of radiation 
pressure.  Radar astronomy has provided detailed information on 
the orbits, sizes, shapes, rotation states, and composition 
of many asteroids.  To improve the capabilities of asteroid radar 
observations, I have developed the technique of radar speckle tracking, 
using  several ground stations during a radar experiment to 
accurately determine the rotation state of the target.
