Until then, all results from the solar radio-spectrographs had been inferred from studying the Sun by looking at its spectrum with only very limited angular resolution. Wild wanted to actually see what these phenomena looked like on the Sun, actually get a moving picture of them. The frequency range that we were interested in was around about the metre wavelengths. To get the resolution roughly equivalent to that of the human eye at these long wavelengths required an aperture some three kilometres in diameter. So I devised a method of synthesising a three kilometre aperture with 96 antennas in a ring.
