Named in honor of Raymond F. Jurgens (1937– ), a radar astronomer at the Jet Propulsion Laboratory, who developed the data-acquisition system used for high-resolution delay-Doppler imaging of (4179) Toutatis in 1992. Jurgens led the dual-polarization, dual-wavelength radar investigations of (433) Eros in 1975 (the first of a minor planet). He also pioneered techniques for using radar spectra to constrain small-body shapes and led the first three-station radar interferometric observations of Venus. (M 23138) _ _.
