Meteor head echoes – observations and models
Abstract. Meteor head echoes – instantaneous echoes moving with the velocities of the meteors – have been recorded since 1947. Despite many attempts, this phenomenon did not receive a comprehensive theory for over 4 decades. The High Power and Large Aperture (HPLA) features, combined with present si...
