| 英文摘要 | Space-based gravitational wave observatories employ inter-satellite laser interferometry system to measure relative displacement between test masses, thereby reconstructing gravitational wave signals. The coupling of telescope pointing jitter with wavefront distortion generates noise in inter-satellite interferometry systems, which may mask measurement signals. Furthermore, the simultaneous effects of pointing deviations and the breathing angle cause continuous variations in the telescope static pointing direction will also exacerbating the coupling noise. Employing analytical derivation and numerical simulation of a coupling model based on the first 21 Zernike polynomials, this study establishes that defocus and astigmatism mediate the influence of static pointing deviations in both horizontal and vertical directions on coupling noise sensitivity, and develops three aberration allocation schemes to suppress this sensitivity. For a wavefront RMS of lambda/30, as the static pointing range expands from 100 nrad to 500 nrad, the probability of meeting the 1 p.m./nrad noise requirement via the proposed optimization scheme increases to 15%-58%, representing a significant improvement over the 2% probability in the unoptimized case. This enables relaxation of static pointing deviation tolerances in telescope control systems while providing theoretical foundations for implementing breathing angle compensation schemes. |
