The invention relates to the technical field of satellites, and discloses a flattened SAR satellite which comprises an SAR load, a satellite platform and a solar wing, the overall configuration of the satellite platform is in a trapezoid shape, the two opposite sides of the satellite platform are parallel to each other, the other two opposite sides of the satellite platform are arranged to be inclined planes, and the SAR load has a folded state and an unfolded state. When a satellite is launched, the SAR load is kept in a folded state to be installed on the top face of the satellite platform, the two solar wings are installed on the inclined faces of the two sides of the satellite platform respectively, the solar wings also have an unfolded state and a folded state, and the solar wings are in the folded state to be folded on the two sides of the satellite platform in the satellite launching state and located in the coverage range of the orthographic projection of the SAR load. According to the flattened SAR satellite, the SAR load folding mode is optimized, the flattened SAR satellite is in an up-down flattened folding state, the configuration of the satellite platform is designed to be a trapezoid body, and the satellite platform tends to be flat, so that the configuration of the SAR satellite is optimized, the space is reasonably utilized, and the envelope size of the flattened SAR satellite is reduced.

    本发明涉及卫星技术领域,公开了一种扁平化SAR卫星,其包括SAR载荷、卫星平台以及太阳翼,卫星平台的整体构型呈梯形体设置,卫星平台的相对两侧相互平行,另一相对两侧设置为斜面,SAR载荷具有折叠状态和展开状态,在卫星发射时SAR载荷保持折叠状态安装于卫星平台的顶面,两个太阳翼分别安装于卫星平台两侧的斜面,太阳翼也具有展开状态和折叠状态,卫星发射状态下太阳翼处于折叠状态收拢于卫星平台的两侧,并且位于SAR载荷正投影的覆盖范围内。该扁平化SAR卫星通过优化SAR载荷收拢方式,成上下扁平折叠状态,并将卫星平台的构型设计为梯形体,使卫星平台趋于扁平,以此优化了SAR卫星构型,合理地利用空间,减小了扁平化SAR卫星的包络尺寸。
