标题： Detecting gravitational waves from inspiraling binaries with a network of detectors : coherent strategies by correlated detectors

摘要： 我们讨论了通过相关激光干涉探测器网络检测双致密天体螺旋并合产生的引力波的相干搜索策略。 从最大似然比统计量中，我们得到了一个略有不同且通常优于我们之前工作中获得的相干统计量。 在两个探测器的交叉谱除以功率谱密度为常数的特殊情况下，新统计量与旧统计量一致。 在简单情况下，也评估了给定虚警率下的检测概率的定量差异。 显示英文摘要

摘要： We discuss the coherent search strategy to detect gravitational waves from inspiraling compact binaries by a network of correlated laser interferometric detectors. From the maximum likelihood ratio statistic, we obtain a coherent statistic which is slightly different from and generally better than what we obtained in our previous work. In the special case when the cross spectrum of two detectors normalized by the power spectrum density is constant, the new statistic agrees with the old one. The quantitative difference of the detection probability for a given false alarm rate is also evaluated in a simple case.
