摘要：
This paper presents the results of initial measurements collected using a compact 60 GHz stepped-frequency continuous-wave (SFCW) imaging radar based on nonlinear transmission lines (NLTLs), and driving a pair of dual-waveguide-fed horn antennas. A range resolution of 2.22 cm is achieved using a bandwidth of over 6.5 GHz, and synthetic focusing is applied to achieve an azimuth resolution of 1 cm with mechanical scanning. The system demonstrates imaging of multiple targets obscured by a large non-metallic interface (cardboard).
