Proposed high order harmonic interferometer for aperture synthesis radio telescope: Theory and computer simulation

A new type of interferometer, called High Order Harmonic Interferometer (HOHI), was proposed by Wu (1996) for imaging by aperture synthesis radio telescope. Its feasibility was proven by theoretical analysis. Before putting HOHI in practical use, computer simulation is a necessary intermediate stage. In this paper the theoretical analysis is reviewed. Then, computer simulation, including its algorithm, calculation and generated maps, is presented. The theoretical analysis is validated by studying these maps.
