The target echo position in two dimensions can be achieved by combining time-domain signals (generated by vector network analyzer or VNA) and orderly variation of optical path difference (contributed from micro-rotation). In this study, the positioning formulas are derived from micro-rotation and small-angle approximation. And to effectively obtain multi-echo position, an approach similar to Klimontovich equation in plasma physics is adopted to image reconstruction function (IRF) which can accurately detect probable positions of target echoes. The proposed method is verified by a three-lens targets experiment. The image reconstruction results precisely showed the positions of the three targets. |
