摘要：

3D range-gated imaging technology is of great significance in application fields such as 3D mapping, long-distance surveillance, navigation, and underwater target detection. The development of 3D range-gated super-resolution imaging technology and the frequently-used 3D inversion algorithms are introduced. On this basis, the 3D range-gated imaging method based on the parabolic envelope is studied. In terms of actual ranging accuracy, depth of field (DOF) of 3D imaging, real-time performance and the difficulty of system implementation, the proposed method is compared with the commonly used triangle and trapezoidal energy-related algorithms and verified by experiments. The results show that the the parabolic envelope-based 3D inversion algorithm reduces the system hardware index requirements, improves the actual ranging accuracy, and meets the demand for real-time large DOF 3D imaging, which demonstrates its good application prospects. © 2022 China Ordnance Society.
