| Popis: | Circular synthesis aperture radar (CSAR) is an efficient way to achieve high-resolution imaging and a common way to realize 3D imaging. In this paper, a multi-antenna receiving (MAR) technique for terahertz radar is presented. In the vertical direction, one antenna transmits radar signal while multi-antenna receives echoes scattered from targets. Data fusion based on threshold selection method is used for different antenna imaging results to get a better image. Imaging quality of the horizontal plane by the proposed technique is remarkably increased. The simulations verify the effectiveness of the proposed technique. |
