CEDAR: Aeronomy of Meteor Trails: Observations, Simulations, and Theory

大孔径雷达观测到的地球上层大气中的流星和流星烧蚀，被用来确定流星和与烧蚀有关的等离子体的基本参数。本研究模拟射电流星回波，建立数值模拟器，提取射电流星的质量、密度、成分和离子中性成分。大孔径雷达对流星周围的等离子体环境进行采样，非镜面流星回波允许提取这些参数。模拟是基于来自ALTAIR、Jicamarca、Arecibo和MU的雷达数据。

Meteors and meteor ablation in the earth's upper atmosphere, as observed by large aperture radars, are used to determine basic parameters of the meteor and of the plasma associated with ablation. The research simulates radio-meteor echoes and creates numerical simulator to extract the mass, density, composition, and ion-neutral composition. The large aperture radars sample the plasma environment immediately surrounding the meteor, and non-specular meteor echoes permit extraction of these parameters. The simulations are based on radar data from ALTAIR, Jicamarca, Arecibo, and MU.
