IMPROVED RADIO MAPPING OF THE SUN

Improved data processing has been applied to the T-shaped 3-cm radioheliograph at Toyokawa. Unwanted harmonics of the signal corresponding to the frequency range beyond the cut-off spatial frequency have been removed. Phase error between the phase centers of the N-S and E-W arrays, which is peculiar to the T-shaped radioheliograph, has also been removed. Smoothing in two dimensions has been made to eliminate the effect of side lobes. It is shown by figures how an original map is refined, step by step, by computer processing, which is a good example of antenna-computer coupling to complete the whole system.
