The Canadian Meteor Orbit Radar







The Western meteor physics group operates a triple-frequency, meteor orbital radar 100 km from London (near Tavistock, Ontario) where  we record ~2500 meteoroid orbits per day. CMOR is a multi-frequency HF/ VHF radar used to detect the ionized trails associated with ablating meteoroids. It has been in single-station operation (echoes) since 1999 and multi-station (orbits) since January of 2002. The radar produces data on the range, angle of arrival, and velocity/orbit in some instances. To the end of 2009 we have measured 4 million individual orbits
