Radar observations of meteors

Abstract

An investigation of short-duration radio echoes observed at 4 to 5 metres wavelength in the neighbourhood of the E region of the ionosphere is described. Observations by vertical beam radio equipments showed that the echoes occurred most frequently at a height of about 95 km. Marked directional characteristics were revealed by the use of equipments with oblique beams, the diurnal variations being different on different bearings.
