EAGER: Ultra High-speed Bandwidth for Performance Improvements in Radar Networks for Weather and Aircraft Surveillance

该项目通过开发直接处理未压缩的高带宽雷达数据的新检测算法，展示了将雷达连接到超高速网络的好处，以改进危险天气警报和响应，以及识别和跟踪小型低空飞行的飞机。虽然雷达网是美国天气观测和飞机监视基础设施的重要组成部分，但今天的互联网被用来将数据从雷达传输到各种最终用户，以便进行决策。为了实现实时传输，雷达数据会被压缩，在此过程中可能会丢失重要信息。通过超高速网络传输未经压缩的雷达数据，可以实现先进的、地理上非常精确的天气灾害检测和预测，从而为公共安全和经济带来好处。此外，跟踪小型低空飞行飞机的能力对于禁毒执法和跟踪用于国土安全和执法的无人机系统非常重要，预计无人机系统将在不久的将来在城市地区普遍使用。该项目将使用位于达拉斯沃斯堡Metroplex的高分辨率、低成本雷达的试验台，与应急经理和国家气象局预报员等用户连接。为了管理由于使用高带宽数据而增加的对处理和联网资源的需求，研究了与按需网络(SDN)和计算资源(云计算)的使用相关的技术。

This project demonstrates the benefits of connecting radars to ultra high-speed networks to improve hazardous weather warning and response and the identification and tracking of small, low-flying aircraft by developing new detection algorithms that operate directly on uncompressed, high-bandwidth radar data. Although radar networks are a critical part of the nation's infrastructure for weather observation and aircraft surveillance, today's best-effort Internet is used to transport data from radars to a variety of end users for decision-making. To allow for real-time delivery, the radar data are compressed and important information can be lost during this process. Transmitting uncompressed radar data over ultra high-speed networks could enable advanced, very geographically precise detection and prediction of weather hazards resulting in benefits to public safety and the economy. In addition, the ability to track, small low-flying aircraft is important for drug enforcement and for tracking Unmanned Aircraft Systems used for homeland security and law enforcement that are expected to be prevalent in urban areas in the near future. The project will be conducted using a test bed of high resolution, low-cost radar located in the Dallas Fort Worth Metroplex linked to users such as emergency managers and National Weather Service forecasters. To manage the increased demand for processing and networking resources from the usage of high-bandwidth data techniques related to the usage of on-demand networks (SDN) and compute resources (cloud computing) are studied.
