论文摘要
环境噪声是观察重力波的关键问题之一，但很难预测。因此，为了评估环境噪声对检测器敏感性的不利影响，了解检测器对实际设置中环境噪声的响应对于观察和将来的升级至关重要。在本文中，我们介绍并验证了一种基于卡格拉后观察后调试的环境噪声喷射测试的新方法。这种新方法（响应函数模型）包括功率的频率转换和非线性，这是Ligo和Pirgo中使用的当前模型（耦合函数模型）中未考虑的效果。我们还通过将其应用于富含环境噪声的数据集并成功地再现方法来确认我们的方法的有效性。
Environmental noise is one of the critical issues for the observation of gravitational waves, but is difficult to predict in advance. Therefore, to evaluate the adverse impact of environmental noise on the detector sensitivity, understanding the detector response to the environmental noise in actual setup is crucial, for both the observation and future upgrades. In this paper, we introduce and verify a new method of the environmental noise injection test based on the post-observation commissioning of KAGRA. This new method (response function model) includes the frequency conversion and nonlinearity of power, which are the effects that are not considered in the current model (coupling function model) used in LIGO and Virgo. We also confirmed the validity of our method by applying it to an environmental noise-enriched dataset and successfully reproducing them.
