Design on the experiment optical system of synthetic aperture imaging lidar

Synthetic aperture imaging lidar is a new active imaging system,which can offer a finer resolution than conventional SAR system,and obtain more dramatic images whose fidelity is close to the optical images.In order to study the relative problem of synthetic aperture techniques of laser wave band,an indoor experiment system of synthetic aperture imaging lidar was given,which simulated imaging of rotating objects using inverse synthetic aperture technology effectively.Firstly,the basic principle of imaging of...
