摘要：

A novel array configuration composed of multiple concentric circles is proposed for sparse aperture imaging systems. To get better image quality, one property of the modulation transfer function, called the practical resolution limit, is chosen as the optimization criterion. The optimized novel array configurations with aperture numbers of 6, 7, 9, 10, and 12 are given by using the simulated annealing algorithm. The comparisons of modulation transfer function with Golay and circle arrays with an equivalent sub-aperture number are implemented. Results show that the optimized arrays have smaller practical resolution limit than other array configurations with relative continuous and uniform coverage in the frequency plane.
