Frequency difference fluctuations of coherent radio signals (32 and 8 cm) scattered by the circumsolar plasma were measured by dispersion interferometry during May to July 1984. Standard deviations of the fluctuations decrease with increasing averaging time according to a power law and increase with approach to the Sun as exponent beta = -1.9. A regular shift of the frequency difference due to the motion of the radio beam with respect to the Sun was observed. The spatial spectrum of plasma turbulence was close to the Kolmogoroff-Obukhov spectrum for frequencies between 0.004 and 0.2 Hz.
