A new azimuth imaging algorithm based on the terahertz single frequency MIMO arc array is proposed in this paper. The MIMO arc array is transformed to the MIMO linear array equivalently, based on which the arc array azimuth image reconstruction is designed and realized by using the RMA algorithm. This paper describes the equivalent transform between the MIMO arc array and the MIMO linear array in detail, constructs the imaging signal model, designs and presents the terahertz single frequency azimuth imaging algorithm based on the MIMO arc array. Finally, the feasibility and effectiveness of the algorithm is verified by computer simulation.%该文提出一种新的在太赫兹频段下基于MIMO弧形阵列的方位向成像算法,通过将MIMO弧形阵列等效转换为MIMO线阵,基于等效MIMO线阵引入RMA算法思路对弧形阵列方位向图像进行重建.该文详细介绍了MIMO弧形阵列与普通MIMO线阵的等效转换,建立了相应的成像信号模型,设计了MIMO弧形阵列太赫兹单频方位向成像算法,并通过计算机仿真验证了该算法的可行性与有效性.
