AST-0618401/Salah, NEROCA flexible and versatile wideband digital spectrometer to be used with the upgraded Haystack 37-m radio telescope will be developed and used for focused science projects and for educational research by graduate and undergraduate students. The Haystack 37-m radio telescope is currently undergoing a major upgrade involving the installation of a new antenna with 0.1 mm surface tolerance. As part of the upgrade, a new wideband low-noise radiometer operating in the band 85 - 115 GHz is being constructed using modern detector technology. In order to fully exploit the new antenna and radiometer capabilities, this work will cover the development of a backend system to process spectral line observations with multiple wideband line coverage.

AST-0618401/SALAH、NEROCA灵活、多功能的宽带数字光谱仪将与升级后的干草堆37米射电望远镜一起使用，将被开发并用于重点科学项目以及研究生和本科生的教育研究。干草堆37米射电望远镜目前正在进行重大升级，包括安装一个表面误差为0.1毫米的新天线。作为升级的一部分，正在使用现代探测器技术建造工作在85-115 GHz频段的新的宽带低噪声辐射计。为了充分利用新的天线和辐射计能力，这项工作将包括开发一个后端系统，以处理具有多个宽带线路覆盖的谱线观测。
