An effective method for identifying shower meteors and determining atmospheric trajectories from single station observations has been developed and tested with computer-simulated and low light level television meteor data. The apparent velocity and calculated height information are used to reduce significantly the number of test radiants in the shower identification algorithm. With typical data the technique permits isolation of shower meteors from a sporadic background when the ratio of the number of meteors from a given shower to the total sample size is as low as 1/20 (for a sample size of about 80). The technique has been applied to 3.2 hr of low light level television data (limiting stellar sensitivity approximately +8.5 mag) obtained at a station in Benmiller, Ontario, Canada during the 1984 Orionid shower.
