我们建立了干涉仪网络中仪器噪声的角功率谱模型，该模型映射了引力波背景(GWBS)作为探测器噪声特性、网络结构和扫描策略的函数。我们使用该模型来计算当前和未来的地面实验以及计划中的太空任务的噪声功率谱。我们用一种类似于宇宙微波背景和强度映射实验的语言给出了我们的结果，并将公式与GWB分析中常见的灵敏度曲线联系起来。我们的形式主义是在一个轻量级的Python模块中实现的，我们在这个HTTPS URL上公开了该模块。
We construct a model for the angular power spectrum of the instrumental noise in interferometer networks mapping gravitational wave backgrounds (GWBs) as a function of detector noise properties, network configuration and scan strategy. We use the model to calculate the noise power spectrum for current and future ground-based experiments, as well as for planned space missions. We present our results in a language similar to that used in cosmic microwave background and intensity mapping experiments, and connect the formalism with the sensitivity curves that are common lore in GWB analyses. Our formalism is implemented in a lightweight python module that we make publicly available at this https URL.
