In order to reduce the noise of reconstuted image when imaging high orbit satellites with intensity correlation array,research on array amelioration should be done to improve the quality of intensity correlation imaging.According to intensity correlation principle,the reasons of spatial spectrum measurement noise and phase retrieval noise generation were analyzed.Also,the effect of condenser area of intensity correlation array,detector arrangement spacing and other parameters on imaging quality was analyzed in condition that the number of high-frequency detectors was fixed.The selecting methods of optimal condenser area and the observation baseline was discussed by a mockup experiment.As the experiment results indicate:for the 14 Mv geostationary satellite,the optimal image can be obatined when the shortest array baseline length is 0.61 times as long as the transverse coherence length,and the condenser diameter is 0.46 times as long as the transverse coherence length.The intensity correlation imaging quality can be largely improved by array amelioration.
