Abstract
(1) Apparatus is described with which echoes due to meteors have been observed by radio technique during 1946 June–August. (2) Simultaneous visual and radio echo observations were made during the 1946 Perseid epoch. Good correlation with meteors was obtained for echoes lasting more than 0.5 sec. The correlation with echoes of shorter duration was very poor. (3) The ranges, durations and amplitudes of 1836 echoes are discussed. (4) Data are given for the daily rate of occurrence. (5) An approximate quantitative relationship is given between meteoric ionization and amplitude of the echo, and the extent of the correlation with visual meteors is discussed.Keywords
