Collaborative Proposal: Science with the Allen Telescope Array

艾伦望远镜阵列（ATA）是一个厘米波长的射电望远镜，有可能产生任何其他仪器都无法完成的独特科学。ATA是第一个为天文观测设计的射电望远镜;它将同时进行敏感的SETI（搜寻地外文明）调查以及传统射电天文学的大面积连续谱和光谱调查。ATA的科学是由一些创新的技术发展。ATA可以作为美国设计平方公里阵列（SKA）的原型，SKA是目前处于规划阶段的下一代射电望远镜。 ATA位于加利福尼亚州的Hat Creek，以前是比马毫米波长阵列的所在地，开始将有42个偏移格里高利天线，具有从0.5到11.2 GHz的连续频率响应，最终目标是350个天线。

The Allen Telescope Array (ATA) is a centimeter-wavelength radio telescope with the potential to produce unique science that cannot be done with any other instrument. The ATA is the first radio telescope designed for commensal observing; it will simultaneously produce sensitive SETI (Search for Extraterrestrial Intelligence) surveys as well as large area continuum and spectroscopic surveys for conventional radio astronomy. The science of the ATA is enabled by a number of innovative technical developments. The ATA may serve as a prototype for the US design of the Square Kilometer Array (SKA), a next generation radio telescope currently in the planning phase. Located in Hat Creek, CA, formerly the site of the BIMA millimeter-wavelength array, the ATA will begin with 42 offset Gregorian antennas with continuous frequency response from 0.5 to 11.2 GHz, with an ultimate goal of 350 antennas.
