摘要。流星体在中性大气中飞行时，其高动能足以使其成分电离。来自流星体周围不规则等离子体的雷达回波被称为流星头回波，可以被HPLA雷达系统探测到。这些回波的测量是在2010年12月用MAARSY（中大气Alomar雷达系统）进行的。雷达系统的干涉测量能力允许在雷达波束内以高精度确定流星轨迹。接收到的数据用于获取有关进入速度、源辐射量、观测高度和其他流星体参数的信息。我们的初步结果表明，大多数流星的质量在10−10和10−3 kg之间，而零星流星和双子座流星的平均质量为~ 10−8 kg。
Abstract. During the flight of a meteoroid through the neutral atmosphere, the high kinetic energy is sufficient to ionize the meteoric constituents. Radar echoes coming from plasma irregularities surrounding the meteoroids are called meteor-head echoes, and can be detected by HPLA radar systems. Measurements of these echoes were conducted with MAARSY (Middle Atmosphere Alomar Radar System) in December 2010. The interferometric capabilities of the radar system permit the determination of the meteor trajectories within the radar beam with high accuracy. The received data are used to gain information about entry velocities, source radiants, observation heights and other meteoroid parameters. Our preliminary results indicate that the majority of meteors have masses between 10−10 and 10−3 kg and the mean masses of the sporadic meteors and Gemenids meteors are ∼10−8 kg.
