The invention provides a single-satellite or multi-satellite heavy orbit interference orbit control method based on an effective vertical baseline, and belongs to the technical field of satellite-borne SAR heavy orbit interference. According to the single-satellite or multi-satellite heavy-orbit interference orbit control method, a reference-observation virtual formation model of heavy-orbit interference is established based on an eccentricity rate vector and a relative inclination angle; based on the geometrical relationship between the latitude of the target detection area and the sub-satellite point latitude and the orbital element, obtaining the relationship between the latitude of the target detection area and the effective vertical base line, and determining the virtual formation effective vertical base line of the reference-observation satellite; and taking the effective vertical base line as an evaluation index to obtain an in-plane/out-of-plane orbit control strategy suitable for single-satellite and multi-satellite heavy-orbit interference. The method solves the problem that at present, domestic and overseas are relatively lack of orbit control strategy research of single-satellite heavy-orbit interference, can provide a new method and a new direction for establishing a remote sensing system in China, can also be applied to air-based situation awareness, and provides support for perfecting an air-based attack and defense system in China.

    本发明提供了基于有效垂直基线的单星或多星重轨干涉轨控方法,属于星载SAR重轨干涉技术领域。单星或多星重轨干涉轨控方法基于偏心率矢量和相对倾角,建立重轨干涉的参考‑观测虚拟编队模型;基于目标探测区域纬度和星下点纬度与轨道根数的几何关系,得到目标探测区域纬度与有效垂直基线的关系,确定参考‑观测卫星的虚拟编队有效垂直基线;以有效垂直基线为评价指标,得到适用于单星、多星重轨干涉的面内/面外轨控策略。本发明解决了目前国内外相对缺乏单星重轨干涉的轨控策略研究的问题,可为建立我国遥感体系提供新方法、新方向,也可应用于空基态势感知,为完善我国空基攻防体系作支撑。
