In this paper we demonstrate experimentally the performance of a monostatic coherent lidar system under the influence of phase aberrations, especially the typically predominant spherical aberration (SA). The performance is evaluated by probing the spatial weighting function of the lidar system with different telescope configurations using a hard target. It is experimentally and numerically proven that the SA has a significant impact on lidar antenna efficiency and optimal beam truncation ratio. Furthermore, we demonstrate that both effective probing range and spatial resolution of the system are substantially influenced by SA and beam truncation.
在本文中，我们通过实验证明了单基地相干激光雷达系统在相位像差影响下的性能，尤其是典型的主要球差（SA）。通过使用硬目标探测不同望远镜配置下激光雷达系统的空间加权函数来评估性能。实验和数值结果均证明，球差对激光雷达天线效率和最佳光束截断比有显著影响。此外，我们还证明了系统的有效探测范围和空间分辨率都受到球差和光束截断的实质性影响。
