Abstract:

A theory for the dependence of meteoric-echo heights and durations on meteor velocity and magnitude, and on the radio wavelength, is used to interpret experimental meteor data of a variety of types. It is shown that the data set forms a more consistent whole on the assumption of a three-body than of a two-body attachment process. No velocity dependence is found for the ratio of line density to luminosity. An attachment time constant of about 100 sec is deduced for a reference height of 95 km, and a zero-magnitude meteor is found to produce a maximum line density of about 100 electronsm. Combination of the theoretical and experimental results makes possible calculation of the heights and durations of meteor echoes under a full range of conditions. Author
