The correction of ionosphere parameters on the base of vertical and backscatter sounding data by continuous chirp signal

The methods for determining and correction of ionosphere parameters by real-time data of vertical and backscatter data sounding (VS and BS) by continuous chirp signal are presented. The input data are forecast ionosphere parameters and processing and interpretation results for VS and BS ionograms: VS height-frequency characteristic (HFC) and the leading edge of backscatter signal. On the base of the leading edge of BS signal one can calculate VS HFC for given points on the sphere in the sounding sector. On the base of HFC tracks the counting of ionosphere parameters is carried out. On the base extrapolation of the ratio of real to forecast values of ionosphere layer critical frequencies with account of layer geometrical parameters the correction of ionosphere parameters in given sphere points is carried out.
