Abstract:
The work contained in this thesis was carried out at the Physical Research Laboratory, Ahmedabad and describes observations of Interplanetary Scintillation (IPS), carried out since 1984, using a large 10,000 sq m dipole array operating to 103 MHz. During the period of research the array underwent an expansion to 20,000 sq m and the later part of the observations were carried out using the enhanced array.
