    Abstract: 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.
