Abstract
The distribution of the angles of arrival of mesosphere radio echoes has been obtained and studied. Special attention has been paid to the region of altitudes in the vicinity of the mesopause. It has been indicated that the angle of arrival distribution in this region has a maximum near the direction toward the zenith and is anisotropic. At the same time, the average intensity of radio echoes substantially exceeds the background level for any angles of arrival.
