子午工程二期流星雷达样机测试及数据对比分析

Meteor radar prototype testing and data quality comparison analysis for Phase II of Chinese Meridian Project

  • 摘要: 子午工程二期将在分布于全国的10个观测站点建设流星雷达. 为了带动国内空间环境地基观测技术的发展,工程建设项目指挥部布局了流星雷达的国产化专项行动. 为了确保建成后的设备满足使用要求,工程总体组织了设备样机测试,包括设备的技术指标测试和数据质量评估. 技术指标测试表明其满足要求. 在获得数据之后,以EMDR流星雷达数据为参考,对样机的数据进行质量评估. 主要对比参数包括有效流星计数、流星数时空分布、扩散系数高度分布、风场随高度的分布和随时间的变化等. 本文主要展示了数据质量评估的结果,揭示了流星雷达观测的一些基本特征和规律,为数据准确性的评估提供参考和借鉴.

     

    Abstract: The Phase Ⅱ of Chinese Meridian Project will deploy 10 meteor radar systems in China. To promote the advancement of domestic ground-based observation technologies, the project managing headquarters are engaged in a special campaign for the localization of meteor radar production. To ensure that the domestically manufactured product meets the requirements, prototype testing was carried out, including a technique indicator test and data quality evaluation. According to the results of the field technique indicator test, the prototype fully met the requirements. Further, the data quality was evaluated using the EMDR meteor radar data as a reference. The main comparison parameters included valid meteor count, space-time distribution of meteor number, height distribution of diffusion coefficient, and distribution of wind field at varying height and time. This study mainly explains data quality evaluation results, revealing some basic characteristics and laws of meteor radar observation, in an attempt to testify the capability of the prototype and provide a reference for future meteor radar data quality evaluation.
