Observation of Interplanetary Scintillation with Single-Station Mode at Urumqi

摘要

The Sun affects the Earth's physical phenomena in multiple ways, inparticular the material in interplanetary space comes from coronal expansion inthe form of inhomogeneous plasma flow (solar wind), which is the primary sourceof the interplanetary medium. Ground-based Interplanetary Scintillation (IPS)observations are an important and effective method for measuring solar windspeed and the structures of small diameter radio sources. We discuss one modeof ground-based single-station observations: Single-Station Single-Frequency(SSSF) mode. To realize the SSSF mode, a new system has been established atUrumqi Astronomical Observatory (UAO), China, and a series of experimentalobservations were carried out successfully from May to December, 2008.
