Based on the traditional array configuration, including the annulus, Golay-6 and the Tri-arm, two ways for designing multiple-array configurations are investigated. Then the simulation with the multiple-array configurations are fulfilled with the specific system parameters. The direct imaging results and the restored images are obtained. By using the correlation coefficient as the evaluation criterion of imaging, the results show that different designs of the multiple-array configurations may produce the different quality of the imaging. It should consider the characteristics of the main-array to choose its sub-array configuration and to optimize the array.
