Experimental results demonstrate that, under indoor short-range conditions, the proposed method improves spatial resolution by approximately a factor of two and increases imaging speed by about 91 times compared to conventional scanning-based approaches. In long-range outdoor experiments, the team successfully performed NLOS imaging at a distance of 3.3 km. With only about 3 minutes of acquisition time, they reconstructed clear images of hidden targets with spatial resolution better than 3 cm.
