Radiophysics and Quantum Electronics
We present the results of experimental studies of an artificial ionospheric turbulence, which were obtained using the radio-direction finder ionosonde with linear frequency chirp of output signal. Several scattered signals with close distance-frequency and angular-frequency characteristics were observed, which is related to radio-wave scattering by various clustered areas. The features of the aspect scattering of radio waves on the IZMIRAN-"Sura"-Rostov-on- Don path were simulated. The spatial dimensions and the structure of the region filled by small-scale artificial ionospheric irregularities are estimated. The displacement of some clusters from the main region is of the order of 10-40 km with the smaller and larger displacements observed in the daytime and evening ionospheres, respectively. © 2012 Springer Science+Business Media, Inc.
