摘要

寄生合成孔径雷达编队可以利用较小的卫星进行低空飞行,为传统的合成孔径雷达任务增添了潜力。在此范围内,本文提出了一个与 PLATiNO-1 号卫星编队飞行的沿轨道分布式寄生接收器的案例研究。编队维护是本文的核心贡献,突出了对高度和平面内异常的主动控制如何导致不可行的ΔV。然后,提出了围绕标称值对高度进行主动控制的方法,这自然会控制异常偏移。结果表明,年 ΔV 可以降低到 m/s 的范围。

Case Study of Along-Track Separation Maintenance of Distributed Synthetic Aperture Radar Systems in Low Earth Orbits
Parasitic SAR formation can be flown at low altitude using smaller satellites and adding potential to conventional SAR mission From the orbital point of view, the main issue is related to the differential aerodynamic drag, which rapidly disrupts the formation. In this ambit, this paper proposes a case study of an along-track distributed parasitic receiver flying in formation with PLATiNO-1. Formation maintenance is the core contribution, highlighting how the active control of both altitude and in-plane anomalies leads to an unfeasible ΔV. Then, the active control of the altitude around the nominal value, which naturally controls anomaly shift, is proposed, modeled, and applied to the presented case study. It is shown that the annual ΔV can be reduced to the m/s range.
