Radio interferometric observations of solar bursts in the decimeter range with the millisecond temporal resolution

Radio interferometric equipment for observations of solar decimeter spike-like events with a millisecond time resolution is described. The equipment was tested using the two-element interferometer (540 MHz) of the RAS NIRFI 'Staraya Pustyn' with a baseline of 416 m in October-November 1993 and September-October 1994. More than 20 radio bursts were detected with a time resolution of 0.256 ms. The rise and fall timescales of spikes were as a rule from 50 to 200 ms. The bursts with time scales less than 20 ms were absent in this observation set. A real possibility to measure with 1-2 arcsec precision the dynamics of radio source bright centers during intensive bursts is shown.
