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.

如大孔径雷达所观察到的那样，地球上层大气中的流星和流星消融用于确定流星的基本参数和与消融相关的血浆的基本参数。 该研究模拟了无线电回声，并创建数值模拟器来提取质量，密度，组成和离子中性组成。 大的孔径雷达采样了立即围绕流星的血浆环境，而非特定的流星回声允许提取这些参数。 模拟基于来自Altair，Jicamarca，Arecibo和MU的雷达数据。
