Query: Lunar Imaging and Ionospheric Calibration for the Lunar Cherenkov
  Technique   The Lunar Cherenkov technique is a promising method for UHE neutrino and
cosmic ray detection which aims to detect nanosecond radio pulses produced
during particle interactions in the Lunar regolith. For low frequency
experiments, such as NuMoon, the frequency dependent dispersive effect of the
ionosphere is an important experimental concern as it reduces the pulse
amplitude and subsequent chances of detection. We are continuing to investigate
a new method to calibrate the dispersive effect of the ionosphere on lunar
Cherenkov pulses via Faraday rotation measurements of the Moon's polarised
emission combined with geomagnetic field models. We also extend this work to
include radio imaging of the Lunar surface, which provides information on the
physical and chemical properties of the lunar surface that may affect
experimental strategies for the lunar Cherenkov technique.
