Synthetic aperture imaging is treated as a confocal process. The point-spread function of the synthetic aperture process is narrower than that of conventional imaging by a factor of 0.5, whereas the conventional confocal process offers resolution improvement of a factor of 0.72. The resolution in the regime between conventional confocal and conventional synthetic aperture is explored by computer simulation. Also, experimental results are given.
