Radar Reflexions from Auroras


RADIO echoes on a frequency of 46 Mc./s. have been reported by Lovell, Clegg and Ellyett1. They have been observed also on a frequency of 32.7 Mc./s. by McKinley and Millman2, incidental to their studies of meteor ionization. More recently, a systematic search for such echoes has been made at Saskatoon, Canada, using radar equipment having frequencies of 3,000 Mc./s. and 106.5 Mc./s. During this search, echoes have been observed regularly on the lower frequency but not at all on the higher one.
