The configuration of the interferometric array can affect the quality of a restored image. In this paper, an iterative array configuration optimization method is proposed. This method uses simple prior information of the observed target, an image reconstruction algorithm, and a Monte Carlo search method to find an optimal array configuration. The advantage of this method is that it can directly use image quality as the evaluation criterion to optimize the array configuration. The optimized Y-shaped arrays with a given number of apertures and the restored images are shown in the simulation and the experiment. The results show that the optimized arrays obtained images close to the ideal optimized results. (C) 2018 Optical Society of America
