Abstract A new Three-Dimensional (3D) scene reconstruction method is proposed to meet the practical application requirement of the active cylindrical scanning millimeter-wave 3D imaging security apparatus. Specifically, the ω-K algorithm is firstly used to realize the decoupling and focusing between the antenna array direction and the range direction, then the synthetic aperture processing between the distance and angle direction is performed to achieve the focusing with the Back Projection (BP) algorithm, realizing the fully 3D scene reconstruction. The echo data processing results of the simulated and measured 3D human model show that this method is theoretical feasible with good practical applicability. Besides, the proposed method could realize the fast and accurate 3D human imaging by CUDA platform and be applicable to the nonideal cylindrical scanning 3D imaging scenarios.
