This note will consider the reconstruction of the sky from the measured visibilities from a
pair of cylinder antenna arrays. It is assumed that the cylinders fixed and are oriented along the
meridian. Each cylinder is populated with N feeds spaced uniformly along the length. The output
voltage of each feed provides an input of a spatial Fourier transform along the cylinder length.
The spatial Fourier transform forms N beams along the length of the cylinder.
