N2 - Multiple-input-multiple-output (MIMO) arc array radar is a novel radar, which can obtain higher azimuth resolution and richer multi-angle information of targets with fewer array elements. However, the imaging efficiency of traditional wideband MIMO arc array radar is limited by the large amount of echo data. Single-frequency MIMO arc array radar has less echo data and the potential for efficient imaging, but the existing imaging algorithms cannot meet the requirements of practical applications. In this paper, we propose a fast 3D imaging method for near-field targets based on single-frequency MIMO arc array radar. After performing geometry-conversion compensation and matched filtering on the echo signal, the proposed method projects the echo spectrum into the image space, to reconstruct the 3D image of near-field targets. The advantages of the proposed method are low computational complexity and high imaging efficiency. Numerical simulation verifies the imaging performance of the proposed method.
