Shackleton crater at the Moon's south pole has been suggested as a possible site of concentrated deposits of water ice, on the basis of modelling of bi-static radar polarization properties and interpretations of earlier Earth-based radar images. This suggestion, and parallel assumptions about other topographic cold traps, is a significant element in(More)
We describe new 70-cm wavelength radar images of the lunar near-side and limb regions obtained via a syntheticaperture-radar patch-focusing reduction technique. The data are obtained by transmitting a circularly polarized pulsed waveform from the Arecibo telescope in Puerto Rico and receiving the echo in both senses of circular polarization with the Robert(More)
Introduction: NASA's exploration plans for the Moon are being driven at least in part by the possibility that there may be exploitable deposits of water ice at the lunar south pole. Whether the elevated hydrogen abundance measured by Lunar Prospector corresponds to water ice and, if so, in what form is still a matter of conjecture. Bi-static radar(More)
