论文摘要
在绕地球进行了两年的无拖放飞行中进行高度敏感的加速度测量之后，显微镜为迄今为止弱等效原理（WEP）提供了最佳的约束。除了是技术挑战之外，该实验还需要专门的数据分析管道，以寻找埋在噪声中的潜在小信号，可能会因仪器缺陷，缺失数据和故障而困扰。本文介绍了我们为显微镜开发的频域迭代最小二乘技术。特别是，使用数值模拟，我们证明我们的估计器是公正的，并提供了正确的误差线。因此，本文证明了显微镜给出的WEP测量的鲁棒性。
After performing highly sensitive acceleration measurements during two years of drag-free flight around the Earth, MICROSCOPE provided the best constraint on the Weak Equivalence Principle (WEP) to date. Beside being a technological challenge, this experiment required a specialised data analysis pipeline to look for a potential small signal buried in the noise, possibly plagued by instrumental defects, missing data and glitches. This paper describes the frequency-domain iterative least-square technique that we developed for MICROSCOPE. In particular, using numerical simulations, we prove that our estimator is unbiased and provides correct error bars. This paper therefore justifies the robustness of the WEP measurements given by MICROSCOPE.
