The low flflux of ultra-high-energy cosmic rays (UHECRs) makes it challenging to understand their
origin and nature. A very large effffective aperture is provided by the Lunar Askaryan technique.
Particle cascades in a dielectric medium produce radio emission through the Askaryan effffect.
Ground based radio telescopes are used to search for nanosecond radio pulses that are produced
when cosmic rays or neutrinos interact with the Moon’s surface. The LOw Frequency ARray
(LOFAR) is currently the largest radio array operating at frequencies between 110 − 190 MHz;
the optimum frequency range for Lunar signal search and 30 − 80 MHz for radio detection of air
showers. One minute of observation has been carried out with six LOFAR stations beam-formed
towards the Moon. In this contribution, we present some preliminary results of the analysis of the
data and a complete description of the analysis steps
