Heliograph of the UTR-2 Radio Telescope. III. Observations

Abstract

The third part of the work dealt with the heliograph of the UTR-2 radio telescope description shows that every pixel from the signal received by the corresponding beam of the antenna pattern is the crosscorrelation dynamic spectrum (time-frequency-intensity) measured by the digital spectrum processor in real time. This new generation heliograph allows the solar corona images within 8÷33 MHz with the 4 kHz frequency resolution, time resolution to 1 ms, and for a 90 dB dynamic range. The illustrations of observations of solar corona and other radio sources made in summer of 2010 with the heliograph are demonstrated.
