Multi-target echo positions in two dimensions can be achieved by combining time-domain signals of vector network analyzer (VNA) and orderly variation of optical path contributed from two-antenna slippage. In this study, the positioning formulas are derived based on the concept of Bragg's law of X-ray diffraction. To effectively obtain multi-echo positions, 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 has successfully been verified by a series of randomly arranged three-target experiments. The image reconstruction results precisely showed the positions of targets. |
