DESCRIPTION:The ultra-high-energy end of the spectrum of cosmic rays is cr
 itical for understanding the nature and origin of these particles.  Howeve
 r\, the low flux of cosmic rays at these energies necessitates the use of 
 extremely large detectors.  The largest potential aperture is offered by t
 he use of the moon as the detector\, with ground-based radio telescopes us
 ed to detect the nanosecond-scale pulse produced when an ultra-high-energy
  particle interacts in the lunar regolith.  I will review the motivation a
 nd history of these experiments\, covering the specialised techniques requ
 ired to detect pulses on such short timescales and the evaluation of the r
 esulting limits on the fluxes of ultra-high-energy cosmic rays and neutrin
 os.\n
