Abstract : Two particular types of distribution of heliocentric meteor radiants are considered. The corresponding expressions of the volume density of radar echoes are determined by introducing for the heliocentric velocity distribution the parabolic-step approximation, described. This kind of approximation allows one to obtain for the volume density of echoes an expression which can easily be evaluated numerically by means of an electronic computer. In sec. 6, a program of numerical calculations is described which will allow one to derive some interesting information about the actual distribution of heliocentric radiants and velocities of meteors.
