Observations of scintillation index and solar wind velocity using a grid of sources at 327MHz, enable us to study the radial evolution of enhanced scintillation regions between 0.3-1.0 a.u. and at a large range of heliocentric latitudes. Statistical analysis as well as the study of specific events during the declining phase of the solar cycle, show that enhanced scintillation regions associated with compressed plasma density due to the interaction between fast and slow solar wind flows, develop only beyond 0.5 a.u. At distances less than 0.5 a.u., the scintillation index varies in a similar manner to the variations in plasma density as observed by space probes at the same distances from the Sun.
