Abstract :
Experimental results of HF radio waves scattering from artificial irregularities induced by "Sura"heating facility FMCW (chirp sounding) method as a diagnostic tool are presented. Elimination of the disturbed region of the ionosphere was performed from the point IZMIRAN, distant from "Sura" on about 500 km, and the scattered on the artificial irregularities signals were received at the distances 120 km, 560 km and 1100 km correspondently. An analysis of the simultaneous observations has shown that total frequency range of the scattered signals can reach up to 10 MHz.
