The invention discloses a satellite-borne high-integration synthetic aperture radar antenna unfolding system, and the system is characterized in that a power supply management module is electrically connected with a + X side driving module and a-X side driving module, and is used for supplying power to the + X side driving module and the-X side driving module; and the + X side driving module and the-X side driving module are electrically connected with the corresponding + X side synthetic aperture radar antenna unfolding mechanism and the corresponding-X side synthetic aperture radar antenna unfolding mechanism, and are used for driving a stepping motor in the synthetic aperture radar antenna unfolding mechanism, so that in-orbit unfolding of the synthetic aperture radar antenna unfolding mechanism is realized. According to the invention, the FPGA is used as a control core to drive the inner plate motor main and standby windings and the outer plate motor main and standby windings of the antenna unfolding mechanism of the synthetic aperture radar, so that the on-orbit unfolding of the antenna unfolding mechanism is realized. In-orbit unfolding of four synthetic aperture radar antennas can be controlled at the same time, the overtime automatic rotation stopping function is achieved, and a synthetic aperture radar antenna unfolding mechanism is effectively protected.

    本发明公开一种星载高集成合成孔径雷达天线展开系统,供电管理模块分别与+X侧驱动模块和‑X侧驱动模块电连接,用于为+X侧驱动模块和‑X侧驱动模块供电;+X侧和‑X驱动模块与各自对应的+X侧和‑X侧合成孔径雷达天线展开机构电连接,用于驱动合成孔径雷达天线展开机构中的步进电机,进而实现合成孔径雷达天线展开机构的在轨展开。本发明以FPGA为控制核心完成合成孔径雷达天线展开机构的内板电机主备绕组和外板电机主备绕组驱动,进而实现天线展开机构的在轨展开。可同时控制共计4块合成孔径雷达天线的在轨展开,具备超时自动停转功能,有效保护合成孔径雷达天线展开机构。
