A new non-redundant double-circle sparse aperture array configuration,which is composed of two uniform circle arrays,is proposed,since the modulation transfer function (MTF) of the common uniform circle array usually has zero-value regions within the cut-off spatial frequency,which prejudice the image quality. The pupil function and MTF have been given. Taking the five-three double circles array as an example,image performance is discussed in terms of the sub-aperture diameter,inner circle radius and inner circle rotation,based on the practical cut-off frequency. Imaging simulation and image restoration are given. The results show that,compared with the uniform circle array and Cornwell′s optimized circle array,the double circle array has higher practical cut-off frequency,and the image quality degrades with the decrease of filling factor.
