摘要
在典型环形、典型Golay-6型和典型Y型阵列结构的基础上，研究了两种不同的复合孔径阵列构造方式.利用仿真实验对系统进行模拟成像及图像重构，并运用相关系数对成像结果进行评价.结果表明:对不同类型的复合孔径阵列，构造方式对成像质量的影响是不同的，并不具有一致规律;应针对主阵列结构的特征去选择其子阵列的构造方式，做到阵列优化.
Abstract
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.
