摘　　要：提出了一种合成孔径激光成像雷达(SAIL)光学成像处理器的原理方案,基于侧视/直视SAIL单点目标回波收集方程,对此光学处理器的数据加载时空坐标转换、成像分辨率、成像处理能力等方面进行了理论分析,并进行了实验验证,给出了SAIL大口径验证样机获得的目标回波数据的成像结果。此SAIL光学处理器结构简单、紧凑、功耗低,且具有实时、实地处理SAIL回波信号的能力,在未来机载、星载SAIL系统中有广泛的应用前景。A principle scheme of optical synthetic aperture imaging ladar （SAIL） processor is proposed, the temporal-spatial conversion, imaging resolution and the processing capability of this processor are analyzed by the virtue of data collection equation of side-looking/down-looking SAIL, verified experiment is performed, and the imaging results of the collected data of our SAIL demonstrator are displayed. The optical SAIL processor is compact, lightweight and has the ability to real-timely and on-site process the SAIL data, which has a promising application prospect in onboard and satellite borne SAIL systems.
