Scientific paper

The difficulties faced by radio astronomers in reconstructing images without phase information are reviewed. Very long baseline interferometry investigations of the Sun and radio sources show that mistakes can arise if assumptions about brightness distribution are inaccurate. If baselines are not small enough to include all the flux density, objects can be missed. There appear to be fundamental difficulties in reconstructing images of complicated objects without phase.
