Abstract :
Millimeter wave have many advantages compared with microwave, a millimeter wave radar system based on stepped frequency pulse signal can be used to near-field imaging. The wave number domain algorithm is used to mechanical scanning data that achieved by a two-dimensional (2-D) planar aperture with the radar system to reconstruct three-dimensional (3-D) reflectivity image. Results show the efficiency and accurate image reconstruction and highly resolution.
