Study on synthetic aperture imaging lidar based on a laboratory-scale sliding guide system

Synthetic Aperture Imaging Lidar (SAIL) is an extension of conventional microwave Synthetic Aperture Radar (SAR) to much shorter wavelengths (by a factor of about 100,000). This kind of active imaging radar can offer finer resolution and better image feature which is closer to optical image. In this paper, we introduce our laboratory-scale SAIL system in detail, elaborate difficulties that we have solved and will solve, and report our infrared optical synthetic aperture image of a fixed, diffusely scattering target with an aperture moving along with a sliding guide.
