Development of Correlator for the Allen Telescope Array

第一个能够将来自350个天线的信号相关联的成像相关器将被开发出来。该相关器将能够处理比任何其他现有仪器多两个数量级的基线，将具有200兆赫带宽，并将成为同类中第一个能够主动减缓干扰的相关器。该设计将允许测量所有偏振产品，并将使用最新的商业现成数字技术。该相关器将成为平方公里阵列中更大的相关器的原型。该仪器将成为艾伦望远镜阵列的一部分，这是一个私人资助的厘米波射电望远镜阵列。资助相关器将使加州大学伯克利分校射电天文实验室能够继续其培养射电天文学家的传统，这些天文学家在观测射电天文学和仪器方面都很熟练，这对射电天文学的未来至关重要。公众宣传，特别是在K-12年龄段，是ATA项目的一个组成部分：一个由私人资金建造的游客中心将是天文台的一部分。

The first imaging correlator capable of correlating signals from 350 antennas will be developed. The correlator will be capable of processing two orders of magnitude more baselines than any other existing instrument, will have 200 MHz bandwidth and will be the first correlator of its kind capable of active interference mitigation. The design will allow measurement of all polarization products and will use the latest commercial-off-the-shelf digital technology. The correlator will be a prototype for a much larger correlator for the Square Kilometer Array. The instrument will be part of the Allen Telescope Array, a privately funded centimeter-wave radio telescope array. Funding the correlator will enable the UC Berkeley Radio Astronomy Laboratory to continue in its tradition of producing radio astronomers skilled in both observational radio astronomy and instrumentation, critical skills for the future of radio astronomy. Public outreach, especially at the K-12 ages is an integral part of the ATA project: a visitor center built from private funds will be part of the observatory.
