abstract:In astronomy, interplanetary scintillation refers to random fluctuations in the intensity of radio waves of celestial origin, on the timescale of a few seconds. It is analogous to the twinkling one sees looking at stars in the sky at night, but in the radio part of the electromagnetic spectrum rather than the visible one.
The results of recent 30yearsstudyofsolar wind using the methodofradio wave scatteringare reviewed, with emphasis on the interplanetaryscintillation(IPS).
