时域无线电SETI信号检测器的比较
Comparison of signal detectors for time domain radio SETI
摘要：
无线电搜寻地外文明（SETI）的目的是通过探测工程传输来识别宇宙中的智能和通信文明。在没有关于预期信号的先验知识的情况下，SETI检测管道需要高灵敏度、多功能性和有限的计算复杂度，以最大化搜索参数空间并最小化错过的概率。本文将SETI探测问题作为一个二元假设检验问题来处理，并比较了四种利用单接收器射电望远镜收集的数据的人工特征的探测方案。经过理论比较后，这些探测器被应用于美国西弗吉尼亚州绿岸望远镜收集的真实数据。
英文摘要：
The radio Search for Extra Terrestrial Intelligence (SETI) aims at identifying intelligent and communicative civilizations in the Universe through the detection of engineered transmissions. In the absence of prior knowledge concerning the expected signal, SETI detection pipelines necessitate high sensitivity, versatility, and limited computational complexity to maximize the search parameter space and minimize the probability of misses. This paper addresses the SETI detection problem as a binary hypothesis testing problem, and compares four detection schemes exploiting artificial features of the data collected by a single receiver radio telescope. After a theoretical comparison, those detectors are applied to real data collected with the Green Bank Telescope in West Virginia (USA).
