Interplanetary Scintillation, Single Station-Single Frequency, Single Station Dual-Frequency, Simulation
Scientific paper
The sun has the biggest effect on the Earth in many ways. Observing the solar wind is an important method to study the solar-earth environment. Ground-based interplanetary scintillation observations are an effective method of monitoring solar wind speed, studying the random fluctuations of the interplanetary plasma and the structures of radio sources. Two modes of single-station observations, namely, single station-single frequency (SSSF) and single station dual-frequency (SSDF), are briefly introduced and numerically simulated in this paper. The SSSF mode are easier to carry out and has been widely used. Although the observing system and data processing system of the SSDF mode are more complicated, it can measure the solar wind speed more accurately. A new SSDF system is under construction in Miyun, NAOC (the National Astronomical Observatories, Chinese Academy of Sciences), with a 50 m telescope, which will serve the Meridian Project, and this paper is devoted to preparing for this new system.
