| Abstract: | Synthetic Aperture Radar,which makes use of optical heterodyne detection,is drawing more and more attention.The optical heterodyne experiment using a diode pumped solid-state laser is made,and the returning weak signal from the target is found.Then some further experiments are designed to detect diffuse reflection targets,that is,noncooperation targets.The necessary conditions for the application of optical heterodyne detection in synthetic aperture radar are summarized. |
