我们讨论了一种分析干涉引力波探测器数据的方法，重点讨论了从激发双星中探测引力波的分层搜索技术。为此，我们提出了新的坐标来对模板空间进行参数化。使用我们的新坐标，我们开发了几种新的两步搜索技术，这将大大减少计算成本。当我们需要实现${\ensureath{\chi}}^{2}$测试作为检测标准时，这些技术变得更加重要。
We discuss a method to analyze data from interferometric gravitational wave detectors focusing on the technique of hierarchical search to detect gravitational waves from inspiraling binaries. For this purpose, we propose new coordinates to parametrize the template space. Using our new coordinates, we develop several new techniques for a two step search, which would reduce the computation cost by a large amount. These techniques become more important when we need to implement a ${\ensuremath{\chi}}^{2}$ test as a detection criterion.
