Scientific paper

We describe a method for producing high-resolution maps of the radiant distribution of meteor activity over the celestial sphere using single-station radio-meteor observations. The method uses a convolution technique and we show how a suitable convolution function can be chosen to enhance the apparent activity of meteor shower radiants. We apply this method to data produced by the Canadian Meteor Orbit Radar system near London, Ontario and show that the daily motion of the radiant can be measured within a fraction of a degree per day. The system has detected a number of weak showers that have not been previously catalogued. We show how the sensitivity of the system can be improved by combining observations from several days.
