Zusammenfassung:The invention relates to a satellite platform attitude maneuvering method for satellite-borne SAR multi-azimuth angle repeat observation. The method comprises the following steps: s1 determining firstly imaged satellite platform attitude maneuvering way, namely, determining the location of a satellite platform at the starting imaging moment, a satellite attitude and a virtual rotation center in the first imaging process; s2, performing sliding beaming imaging, determining the satellite location at the next imaging starting moment; s3, determining the satellite attitude in the maneuvering process between twice adjacent imaging and the virtual rotation center in the next imaging process by combining the distance between the beam center and the scene after maneuvering according to the satellite location at the starting moment of the next imaging, and adjusting the beam pointing to a direction starting location of the scene in the attitude maneuvering adjusting process; and s4, repeating step s2 and s3 until the
