Abstract. In recent years, the concept of multistatic meteor radar systems has attracted the attention of the atmospheric radar community, focusing on the mesosphere and lower thermosphere (MLT). Recently, there have been some notable experiments using multistatic meteor radar systems (Chau et al., 2019; Spargo et al., 2019; Stober and Chau, 2015; Stober et al., 2018). Good spatial resolution is vital for meteor radars because nearly all parameter inversion processes rely on the accurate location of the meteor trail reflecting points. It is timely then for a careful discussion focussed on the error distribution of multistatic meteor radar systems. In this study, we discuss the measurement errors that affect the spatial resolution and obtain the resolution distribution in 3-dimensional space for the first time. The spatial resolution distribution can both help design a multistatic meteor radar system and improve the performance of existing radar systems. Moreover, the spatial resolution distribution allows the accuracy of retrieved parameters such as the wind field to be determined.

多静态流星雷达系统的误差分析以获得3维空间分辨率分布

摘要。近年来，多基地流星雷达系统的概念引起了大气雷达界的关注，重点是中层和低热层（MLT）。最近，使用多流星雷达系统进行了一些值得注意的实验（Chau等人，2019; Spargo等人，2019; Stober和Chau，2015; Stober等人，2018）。好的空间分辨率对于流星雷达至关重要，因为几乎所有参数反演过程都依赖于流星轨迹反射点的准确位置。现在是时候进行针对多静态流星雷达系统误差分布的认真讨论了。在这项研究中，我们讨论了影响空间分辨率的测量误差，并首次获得了三维空间中的分辨率分布。空间分辨率分布既可以帮助设计多点流星雷达系统，又可以改善现有雷达系统的性能。此外，空间分辨率分布允许确定所检索参数（例如风场）的准确性。
