Multipurpose Spectrometer Instrumentation for SETI and Radio Astronomy

这是一个设计和建造用于SETI和射电天文学应用的模块化通用光谱仪的项目。该仪器将主要用于在美国国家科学基金会的阿雷西博天文台进行多波束SETI和天文观测。研究人员正在与几个射电天文小组密切合作，他们将在其他传统射电天文学应用中使用该仪器和/或其技术。该光谱仪是一台20亿通道的仪器，被称为“SERENDIP V”。SERENDIP V系统包含了其他仪器所没有的新功能。SERENDIP V被设计用于与将于2003年安装在阿雷西博望远镜上的七波束接收器系统一起工作。SERENDIP V系统将以双偏振方式同时分析来自所有波束的信号，有效地同时观测天空中的7个点。该仪器将用于SETI、HI、连续极化和分散脉冲调查，同时将使用多波束接收器对银河系平面进行大规模脉冲星调查。

This is a program to design and build a modular general-purpose spectrometer for SETI and radio astronomy applications. The instrument will mainly be used to conduct multibeam SETI and astronomical observations at NSF's Arecibo Observatory. The investigators are working closely with several radio astronomy groups who will use the instrument and/or its technology in other traditional radio astronomy applications. The spectrometer is a two billion channel instrument, dubbed "SERENDIP V". The SERENDIP V system includes new capabilities not found in any other instrument. SERENDIP V is designed to operate in conjunction with a seven-beam receiver system which will be installed at the Arecibo telescope in 2003. The SERENDIP V system will analyze signals from all beams simultaneously in dual polarization, effectively observing seven points on the sky simultaneously. This instrument will be used to perform SETI, HI, continuum polarization, and dispersed pulse surveys concurrently with a large-scale pulsar survey of the galactic plane that is to be performed using the multibeam receiver.
