9418248 Davis This research is to study the core-mantle boundary by means of seismic array analysis. The new methods to be used include the directional determination ability of arrays and signal processing techniques developed in the RADAR community. Data from several seismic arrays throughout the world will be used to explore the topography and reflective properties of the core-mantle boundary, which is a key feature in the development of competing mantle convection models. The results of this study will be compared with earlier tomographic work based upon travel-time analysis alone. *** ??

小行星9418248 本研究是利用地震台阵分析方法研究核幔边界。 将使用的新方法包括阵列的定向能力和雷达界开发的信号处理技术。 来自世界各地几个地震台阵的数据将用于探索地核-地幔边界的地形和反射特性，这是开发相互竞争的地幔对流模型的一个关键特征。 这项研究的结果将与早期的层析成像工作的基础上旅行时间分析。 *** ??
