  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.
