LIV. A radio echo apparatus for the delineation of meteor radiants

This paper describes a radio echo apparatus for the continuous recording of meteor activity, and the determination of the coordinates of active meteor radiants. It has been in operation since September 1949, and the occurrence of well known night time showers during this period have provided an opportunity to estimate its performance. The results obtained during the Geminid shower of 1949 and 1950 are described as an example, and its accuracy and resolving power are discussed.
