本论文描述了一个用于预测天基远红外干涉仪性能的端到端仿真器的物理和计算方面。本论文还包括，科学能力和仪器的最先进的。后者是雄心勃勃的下一步，远红外天体物理学界需要采取的，以改善无论如何在这个波长区域的最新和当前的空间望远镜的结果。本文概述了这样的使命所涉及的要求，并描述了最有前途的技术，以捕捉大部分的天体物理信息相结合的光谱空间干涉仪。这种系统的模拟非常复杂，需要多次傅立叶变换，每个傅立叶变换都受到仪器非理想性和适当的优化技术的影响。作为结论，本文提供了一个例子，这样的仪器可以实现的基本性能时，针对年轻的星星形成区。
This thesis describes the physics and computational aspects of an end-to-end simulator to predict the performance of a Space-based Far Infrared Interferometer. The present thesis also includes, the science capabilities and instrumental state-of-the art. The latter is the ambitious next step which the Far-Infrared Astrophysical community needs to take to improve in anyway on the results of the most recent and current space telescopes in this wavelength region. This thesis outlines the requirements involved in such a mission and describes the most promising technique to capture most of the astrophysical information by combining spectroscopy to spatial interferometer. The simulation of such a system is extremely complex requiring multiple Fourier transforms each of which is subject to instrument non-idealities and appropriate optimization techniques. As a conclusion, the thesis provides an example of the basic performance achievable with such an instrument when targeting a young star formation region.
