Abstract. The radar system described here (CMOR) comprises a basic 5-element receiving
system, co-located with a pulsed transmitter, specifically designed to
observe meteor echoes and to determine their position in space with an
angular resolution of ~1° and a radial resolution of ~3 km.
Two secondary receiving sites, a few km distant and arranged to form
approximately a right angle with the base station, allow the determination
of the velocity (speed and direction) of the meteor that, together with the
time of occurrence, lead to an estimate of the orbit of the original
meteoroid. Some equipment details are presented along with a method used to
determine the orbits. Representative echoes are shown and observations on
the 2002 Leonid shower presented.
