ABSTRACT

A broadband analog-digital heliograph based on the UTR-2 radio telescope is described in detail. This device operates by employing the parallel-series principle when five equidistributed array pattern beams which scan the given radiosource (e.g. solar corona) are simultaneously shaped. As a result, the obtained image presents a frame of 5 × 8 pixels with the space resolution 25'× 25'. Each pixel corresponds to the signal from the appropriate pattern beam.
