摘要
利用激光外差探测原理实现综合孔径激光雷达探测越来越受到关注。文中通过二极管泵浦固体激光外差探测实验,实现了实验平台上接受目标反射微弱回波信号的外差探测,并进一步实现了对表面粗糙的若干漫反射目标,即不合作目标的外差探测。总结了实现激光外差探测应用于综合孔径激光雷达领域的必要条件。
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 re- flection targets, that is, noncooperation targets. The necessary conditions for the application of optical hetero- dyne detection in synthetic aperture radar are summarized.
