RÉSUMÉ

The third part of our work describing the UTR-2 array based heliograph shows that every pixel of a signal received from the corresponding antenna pattern beam is the cross-correlation dynamic spectrum (time-frequency-intensity) measured in real time with the digital spectrum processor. This new generation heliograph gives the solar corona images in the frequency range 8 − 33 MHz with the frequency resolution 4 kHz, time resolution to 1 ms, and dynamic range 90 dB. The heliographic observations of radio sources and solar corona made in summer of 2010 are demonstrated.
