... DIAGNOSTICS OF IONOSPHERIC IRREGULARITY SPECTRUM USING MEASUREMENTS OF RADIO WAVE ANOMALOUS ATTENUATION UNDER VERTICAL SOUNDING . ... The selected experimental data are characterized by a high average level of attenuation of a signal of vertical sounding (10 dB and above), which cannot be caused by collisional absorption of radio waves (practically absent in a dark time of day) and, hence, being a consequence of scattering on random irregularities. ... ATTENUATION OF A VERTICAL SOUNDING SIGNAL . ...

... Research objects and scientific purposes . Space scientific program includes development and launch of two supersmall spacecrafts "Universitetskiy" and "Kompas-2" intended for monitoring of radiation conditions near the Earth. ...
