In order to improve the detection capability of small targets such as UAVs, this paper uses a self-developed multi-band polarization imaging detection system to obtain UAV intensity images and polarization images in different ground backgrounds. Through comparative research, it is found that in visible light, near-infrared and far-infrared bands, whether in sunlight or shadow, using polarized images can better find UAVs located on sandy, stone and concrete backgrounds. However, drones on grassy backgrounds are easier to be found in polarized images only when they are not exposed to direct sunlight. Based on various detection results, it is easier to find UAVs in various ground backgrounds by using polarization detection systems, which lays the foundation for improving UAV detection capabilities in complex ground backgrounds.
