目前正在计划在未来10至20年内建造几个空间引力波观测站。真实有效的正演模拟将在这些观测站的设计和运行中发挥关键作用。星载干涉引力波探测器的工作方式与地面上的探测器非常不同。复杂的轨道运动、虚拟干涉测量和有限尺寸效应使天基系统的描述复杂化，而非线性控制系统使地基系统的描述复杂化。在这里，我们探讨了基于空间的引力波探测器的正演建模，并引入了一个绝热近似的检测器响应，显着扩展了标准的低频近似的范围。绝热近似将有助于数据分析技术的发展，并改善天体物理参数提取的建模。
Planning is underway for several space-borne gravitational wave observatories to be built in the next 10 to 20 years. Realistic and efficient forward modeling will play a key role in the design and operation of these observatories. Space-borne interferometric gravitational wave detectors operate very differently from their ground-based counterparts. Complex orbital motion, virtual interferometry, and finite size effects complicate the description of space-based systems, while nonlinear control systems complicate the description of ground-based systems. Here we explore the forward modeling of space-based gravitational wave detectors and introduce an adiabatic approximation to the detector response that significantly extends the range of the standard low frequency approximation. The adiabatic approximation will aid in the development of data analysis techniques, and improve the modeling of astrophysical parameter extraction.
