Telescopes for IPS observations

The sun especially the solar wind have influenced our Earth in many ways, and observing the solar wind is an important method to study the solar-earth environment. Interplanetary Scintillation (IPS) observations are an effective method of monitoring solar wind, forecasting the solar-terrestrial space weather and studying the structures of the long distance compact radio sources. Since the discovery of Interplanetary Scintillation, many countries began to use this method to study the solar wind and the interplanetary plasma, so some appropriative radio telescopes were built to achieve these goals. In this paper, we will review some typical IPS radio telescopes and also the current status of IPS study in China.
