穿墙三维成像中，不同的阵列构架会直接影响阵列性能及其适用环境。利用等效阵列原理设计二维多输入多输出（MIMO）阵列，在具体分析一维 STVA阵列具有最短物理尺寸的原理上，提出了利用子阵划分的方法解决等效阵列到 MIMO阵列的去卷积问题。针对去卷积后得到多种 MIMO阵列构型的择优问题，提出了综合尺寸的概念，利用子阵划分后的部分信息衡量去卷积后 MIMO阵列的物理尺寸，最后将这种方法推广至二维 MIMO阵列，设计出适用于穿墙成像的二维 UWB-MIMO阵列，利用仿真实验验证了其在穿墙三维成像中的优异性能。

In the three-dimensional(3-D)through-wall imaging(TWI),imaging performance and appli-cations of the array are greatly affected by its configuration.In this paper,the concept of equivalent aperture is introduced to design the 2-D MIMO array.A method named sub-array segmentation is proposed to resolve the de-convolution problem between the equivalent array and MIMO array,which is derived from the analysis of the split transmit virtual aperture(STVA).Here,STVA has the shortest physical aperture length when given the virtual aperture.To obtain the optimized array after the de-convolution processing,a concept of comprehensive aperture is used to evaluate the physical aperture of the MIMO array by using the information of sub-array segmentation.Finally,the method is extended to the 2-D planar application and a 2-D UWB-MIMO array is designed for TWI to validate the proposed method.
