摘要:

我们使用了SERENDIP III系统和阿雷西博射电望远镜来寻找可能的人造外星信号。在四年的搜索中,我们覆盖了93%的阿雷西博可观测的天空至少一次,44%的天空五次或更多,灵敏度为~3E-25 W/m2。数据被发送到一个400万通道频谱分析仪。从超过1 E +14个独立数据点获得信息,然后通过一套模式检测算法分析结果,以识别不容易识别为人类活动产物的窄带光谱功率峰。我们分别选择了与我们的天空调查中偶然遇到的有趣的附近G矮星相一致的数据,以获得多余功率峰值的建议。这两个数据集中的峰值功率分布与随机噪声一致。我们报告上限可能的信号从恒星调查,并提供最有趣的候选人在天空调查中确定的例子。本文件原计划于2000年出版,现将2000年提交给ApJS的版本原封不动地在此介绍。

英文摘要:

We employed the SERENDIP III system with the Arecibo radio telescope to search for possible artificial extraterrestrial signals. Over the four years of this search we covered 93% of the sky observable at Arecibo at least once and 44% of the sky five times or more with a sensitivity of ~3E-25 W/m2. The data were sent to a 4 million channel spectrum analyzer. Information was obtained from over 1E+14 independent data points and the results were then analyzed via a suite of pattern detection algorithms to identify narrow band spectral power peaks that were not readily identifiable as the product of human activity. We separately selected data coincident with interesting nearby G dwarf stars that were encountered by chance in our sky survey for suggestions of excess power peaks. The peak power distributions in both these data sets were consistent with random noise. We report upper limits on possible signals from the stars investigated and provide examples of the most interesting candidates identified in the sky survey. This paper was intended for publication in 2000 and is presented here without change from the version submitted to ApJS in 2000.
