Proposal Title: 70­cm Wavelength Radar Observations of Mars
ABSTRACT:
While Mars has been studied during a number of favorable oppositions using X­ and S­band radar systems, there
has been no e#ort to characterize the surface using P­band frequencies since 1973. None of these 70­cm
observations survive in digital form. We request 16 hours of observing time to measure the 70­cm backscattering
properties of Mars, to (1) determine the variability in apparent Fresnel reflectivity and rms slope as a guide to the
design of a future Mars­orbital imaging radar system, (2) compare these derived parameters to the properties of the
surface in visible, IR, and thermal IR data, and (3) search for correlations between these properties and changes in
near­surface hydrogen abundance mapped by the Odyssey spacecraft [Feldman et al., 2002].
