论文摘要
Ariel射频模型Arielrad是一个模拟器，旨在应对优化太空任务科学有效负载的挑战并证明其遵守性能要求。 Ariel是大气遥感红外超级球星大调查，已被ESA选为宇宙视觉计划的M4任务，在其4年的初级运营中，将对经过跨性别的大型跨性别型号的大量样本进行首次无偏光谱调查。为了对任务进行准确的研究，Arielrad使用出色动机的噪声模型来估计固定过程引起的贡献，并包括相关和时间依赖的噪声源的边距。我们表明，测量不确定性由光子统计量支配，并且在初级任务寿命期间，可以完成具有约1000个系外行星目标的观察程序。
ArielRad, the Ariel radiometric model, is a simulator developed to address the challenges in optimising the space mission science payload and to demonstrate its compliance with the performance requirements. Ariel, the Atmospheric Remote-Sensing Infrared Exoplanet Large-survey, has been selected by ESA as the M4 mission in the Cosmic Vision programme and, during its 4 years primary operation, will provide the first unbiased spectroscopic survey of a large and diverse sample of transiting exoplanet atmospheres. To allow for an accurate study of the mission, ArielRad uses a physically motivated noise model to estimate contributions arising from stationary processes, and includes margins for correlated and time-dependent noise sources. We show that the measurement uncertainties are dominated by the photon statistic,and that an observing programme with about 1000 exoplanetary targets can be completed during the primary mission lifetime.
