Experimental realization of inverse synthetic aperture Lidar azimuthal imaging

Based on active optical imaging, synthetic aperture Lidar combines the advantages of traditional microwave synthetic aperture radar and laser radar. It can break through the diffraction limit, has extremely high resolution. Space-based synthetic aperture Lidar can give full play to its characteristics of all-day, all-weather, long-distance, high-resolution and fast imaging because it is free from the influence of the atmosphere. Therefore, it has strong application demand and broad development prospects in space target detection. According to the principle and imaging requirements of synthetic aperture Lidar, this paper designs and builds a point target ISAL imaging experiment system, conducts azimuthal imaging experiments, and obtains a result with an azimuthal resolution of 0.42mm at a distance of 1.5m.
