A Method of Two-dimensional MIMO Planar Array Design Based on Sub-array Segmentation for Through-wall Imaging

  In three-dimensional(3-D)through-wall imaging(TWI)applications,imaging performance is directly affected by the configuration of the arrays.In this paper,the concept of equivalent array is introduced to design the 2-D MIMO array.A method named sub-array segmentation is used to circumvent the de-convolution process between the equivalent array and MIMO array.To get the optimum array among the results after the de-convolution,a concept of comprehensive size is used to evaluate the physical size of the MIMO array by using the information of sub-array segmentation,which is inspired by the split transmit virtual aperture(STVA)that has the shortest physical size given the virtual aperture.Finally,a 2-D UWB-MIMO array is designed for TWI as an example to validate the proposed method.
