This device operates by employing the parallel-series principle when five equi-spaced array pattern beams which scan the given radio source (e.g. solar corona) are simultaneously shaped. As a result, the obtained image presents a frame of 5 x 8 pixels with the space resolution 25' x 25' at 25 MHz. Each pixel corresponds to the signal from the appropriate pattern beam. The most essential heliograph component is its phase shift module for fast sky scanning by pencil-shape antenna beams.
