高功率大孔径雷达使流星科学发生了革命性的变化，它可以根据流星头部的回波来进行高度精确的位置和速度估计。本文介绍了一个新的开放源码软件MODA，用于确定这些流星体的日心轨道参数。我们比较MODA与其他目前的方法，分析和数值。我们描述了我们的第三体扰动和大气阻力，以及太阳辐射压力，这是不考虑在其他作品的建模。我们验证MODA对文献中的结果，并用它来计算ALTAIR在2008年观察到的两个小粒子的轨道。
High-power large-aperture radars have revolutionized meteor science by allowing highly accurate position and velocity estimates to be made from meteor head echoes. This paper describes a new open-source software, MODA, for determining the heliocentric orbital parameters of these meteoroids. We compare MODA with other current methods, both analytical and numerical. We describe our modeling of third-body perturbations and atmospheric drag, as well as solar radiation pressure, which is not taken into account in other works. We verify MODA against results from the literature and use it to compute the orbits for two small particles observed by ALTAIR in 2008.
