Named in honor of R. Scott Hudson (1959– ) of the School of Electrical Engineering and Computer Science at Washington State University. Hudson has pioneered techniques for using delay-doppler radar images of an asteroid to estimate its shape, rotation and radar scattering properties, as well as the delay-doppler trajectory of the target’s center of mass, a result that can improve orbit accuracy by several orders of magnitude. His reconstruction of (4769) Castalia is the first reasonably detailed model of the shape of an earth-crossing asteroid. For (4179) Toutatis, Hudson’s inversion defined the non-principal-axis spin state and the ratios of the principal moments of inertia. Hudson’s techniques are a cornerstone of radar investigation of small bodies and open the door to a variety of theoretical studies of these objects. (M 25654) _ _.
