Abstract
We describe the radio interferometric equipment for observation of solar spike-like events at decimeter wavelengths with millisecond time resolution. The equipment was tested using a two-element interferometer (2 RT7, f=540 MHz, baseline 416 m) at the “Staraya Pustyn” radioastronomical station (RAS) of the Radiophysical Research Institute of Nizhny Novgorod (NIRFI) in October–November 1993 and in September–October 1994. Over 20 solar bursts of different durations, which showed considerable interference response, were detected with time resolution 0.256 ms. The typical time variation scale of the bursts was from 50 to 200 ms. Bursts with time scales less than 20 ms were absent. The actual possibility of measuring the displacements of radio source brightness centers with accuracy up to 1–2 arc s is shown.
