MRI: Development of Next Generation Digital Signal Processing Platforms for Astronomy

该计划将使用最新的开源技术，设计和构建一个专门用于射电天文学的新数字信号处理平台（DSP），但也可能应用于其他领域的科学实验。该仪器与现有射电望远镜相结合，将为观测天文学带来新的方法和能力。学生将获得与该项目的各个方面的实践经验，包括通过数据简化和分析的仪器设计和开发。该主要研究仪器奖将资助超宽带DSP的设计和开发。 该平台将用于下一代Event Horizon Telescope的100 Gbps VLBI数字后端，以及Mauna Kea亚毫米阵列的超宽带相关器和相控阵。 它将使事件视界望远镜的灵敏度提高2倍，可能使黑洞事件视界直接成像。

Using newly available open-source technology, this program will design and build a new digital signal processing platform (DSP) specifically for radio astronomy, but with possible applications scientific experiments in other fields. Coupled with existing radio telescopes, this instrument will lead to new approaches and capabilities for observational astronomy. Students will gain hands-on experience with all aspects of the project, including instrument design and development through data reduction and analysis.This Major Research Instrumentation award will fund design and development of an ultra-wideband DSP. This platform will be used for a 100 Gbps VLBI digital back end for the next generation Event Horizon Telescope and for an ultra-wideband correlator and phased array for the Submillimeter Array on Mauna Kea. It will increase the sensitivity of the Event Horizon Telescope by a factor of 2, possibly enabling direct imaging of a black hole event horizon.
