Determining parameters of the layer of scattering irregularities forming coherent echo according to the data from the Irkutsk is radar

This paper presents a method for determining parameters of the layer of scattering irregularities, which form coherent echo, from the Irkutsk Incoherent Scatter Radar data. This method is demonstrated to have the desired precision. The processing of experimental data for the periods of 25-26 September 1998 and 15-16 July 2000 showed a good agreement between our results and the data obtained by other researchers. The analysis of experiments with high time resolution revealed time dependence of the parameters under study. Time change of the layer thickness and height agree with data obtained by other researchers, while the time dependence of angular sensitivity of irregularities has been observed for the first time and invites further investigations
