Fe resonance fluorescence lidar (Fe lidar) is considered an ideal candidate for temperature and wind measurement in the mesosphere and lower thermosphere region. However, considering the complexity of it, only a few Fe lidars have been operated in a few locations. To develop a Fe lidar with high performance, simulation work is the first important step. A simulation model is built in this paper. The expressions for the temperature-wind uncertainties are derived using the error propagation method. Within the limit of saturation effect, an index decomposition of the lidar and atmospheric parameters are performed. When the dwell time and central frequency shift are optimized to 0.205 and 932 MHz at night and 0.212 and 687 MHz during the day, night and daytime calibration curves are acquired, and after confirming the simulation parameters, the performance of Fe lidar is also evaluated. The simulation model could provide a valuable guidance for Fe lidar design.
铁共振荧光激光雷达（Fe激光雷达）被认为是中层大气和低热层区域温度和风测量的理想候选设备。然而，考虑到其复杂性，只有少数几个地方运行了少量的Fe激光雷达。为了开发高性能的Fe激光雷达，模拟工作是首要重要步骤。本文构建了一个模拟模型。使用误差传播方法推导了温度 - 风不确定性的表达式。在饱和效应的限制范围内，对激光雷达和大气参数进行了指数分解。当夜间的驻留时间和中心频率偏移优化为0.205和932 MHz，白天优化为0.212和687 MHz时，获取了夜间和白天的校准曲线，在确认模拟参数后，还对Fe激光雷达的性能进行了评估。该模拟模型可为Fe激光雷达设计提供有价值的指导。
