A Fast and Accurate 3-D Reconstruction Algorithm for Near-Range Microwave Imaging with Handheld Synthetic Aperture Radar
The design of image reconstruction algorithms for near-range handheld synthetic aperture radar (SAR) systems has gained increasing popularity due to the promising performance of portable millimeter-wave (MMW) imaging devices in various application fields. Time domain imaging algorithms including the backprojection algorithm (BPA) and the Kirchhoff migration algorithm (KMA) are widely adopted due to their direct applicability to arbitrary scan trajectories. However, they suffer from time complex…
