Canadian Meteor Orbit Radar (CMOR)

[摘要] The radar system described here (CMOR) comprises a basic 5-element receivingsystem, co-located with a pulsed transmitter, specifically designed toobserve meteor echoes and to determine their position in space with anangular resolution of ~1° and a radial resolution of ~3 km.Two secondary receiving sites, a few km distant and arranged to formapproximately a right angle with the base station, allow the determinationof the velocity (speed and direction) of the meteor that, together with thetime of occurrence, lead to an estimate of the orbit of the originalmeteoroid. Some equipment details are presented along with a method used todetermine the orbits. Representative echoes are shown and observations onthe 2002 Leonid shower presented.
