欧洲空间局的Ariel任务计划于2029年发射，旨在开展首次大规模的凌日系外行星大气光谱巡天。Ariel通过优化设计凌日测光载荷，实现探测时间尺度上的高光度稳定性，以探测化学元素的谱线特征，该设计或消除已知系统误差，或允许在数据处理期间去除系统误差而不会显著降低或偏置探测效果。在测量系外行星大气光谱时，航天器的视轴抖动是一种干扰源。我们描述了一种改进的时域模拟Ariel观测数据的去抖动算法。我们选择一种基于抖动引起的点扩散函数（PSF）畸变的空间信息来对光学信号进行去趋势的方法。该抖动模型基于主承包商Airbus Defence and Space为Ariel服务模块提供的代表性模拟。我们研究了去抖动观测后恢复的大气光谱的精度和偏差。在长波长处，Ariel光谱仪的光度稳定性已受光子噪声主导。我们的算法能有效去除光度数据和光谱数据的抖动，确保在整个Ariel光谱范围内的性能保持光子噪声限制，完全符合任务要求。这项工作为Ariel的数据处理流程开发做出了贡献，与其科学目标一致，也可能对其他天文望远镜和仪器有益。
