论引力波探测器方位与引力波源方位间的关系

DISCUSSION ABOUT THE RELATION OF POSITION BETWEEN GRAVITATIONAL WAVES DETECTORS AND THE SOURCE

本文从计算棒状引力波天线的指向性函数出发,讨论了引力波源的方位和天线棒方位之间的关系,找到了从符合实验数据求出引力波源方位以及利用单一引力波探测器对连续引力波源的定位方法。所得的结果也适用于其他形式的一维引力波天线。一旦引力波探测器的灵敏度达到足以确定引力波强度时,本文的结果无疑对引力波天文学将是很有意义的。

Starting from calculating the directivity pattern of bar-shaped gravitational wave antenna, the relation of position between gravitational waves detectors and source is discussed in this paper. Further, the methods, which is used to determine the position of gravitational wave source, based on the data of coincident experiments, and the position of continuous gravitational wave source, based on the data of single gravitational wave antenna, are obtained. These results are also applicable for other types of one-dimentional gravitational wave detector. Once the sensitivity of the gravitational wave detector reaches the level, enough to determine the intensity of gravitational wave, the results presented in this paper will undoubtedly be useful for gravitational wave astronomy in the future.
