Abstract

We present a maximum entropy imaging algorithm using the bispectrum observed with interferometers. It is iterative and based on the steepest ascent method. Imaging simulation test show that this algorithm can reconstruct more reliable images of weak, extended sources than the conventional self- calibration method.
