摘　　要：文章针对高功耗、长期在轨的低散射模拟伪装卫星对大面积外伸太阳翼的需要,开展了太阳翼构型低散射优化设计研究。太阳翼作为卫星最大的外伸结构,是航天器雷达散射截面(RCS)的主要贡献源之一。面向地面雷达探测,设计了一种低散射模拟伪装星体结构,研究了大面积外伸太阳翼的散射特性缩减方式,设计了不同展开构型的太阳翼并对其散射特性进行了研究。结果表明,在相同的展开面积下,所设计的1∶10展开构型、圆展开及多边形展开式太阳翼相比传统太阳翼在RCS曲线上表现出更少的尖峰,更适用于具有低散射需求的模拟伪装卫星。In order to meet the needs of high-power,long-term in orbit low scattering simulation camouflage satellites for large-area extended solar wings,research on low scattering optimization design of solar wing configurations has been carried out.As the largest extended structure of satellites,solar wings are one of the main contributors to the radar cross section(RCS)of spacecraft.Facing ground radar detection,designed a low scattering simulated camouflage star structure,studied the reduction of scattering characteristics of large-area extended solar wings,designed solar wings with different configurations,and studied their scattering characteristics.The results show that,under the same unfolding area,the designed 1∶10 unfolding configuration,circular unfolding,and polygonal unfolding solar wings exhibit fewer spikes on the RCS curve compared to traditional solar wings,making them more suitable for simulating camouflage satellites with low scattering requirements.
