提高微小卫星的低可观测特性能够有效提升微小卫星的使用效率和生存能力,因此,设计了一种以稀疏A*算法(SAS)为基础的微小卫星低可观测飞行姿态静环境规划算法。通过对微小卫星的俯仰角,方位角和横滚角等姿态角进行调整,从而可以有效降低微小卫星在威胁雷达方向上的RCS值,提高微小卫星的低可观测特性。通过对工作频率在S波段和VHF波段的威胁雷达对微小卫星的威胁性进行仿真,结果显示规划后微小卫星的低可观测性能明显改善,满足飞行姿态规划的需求。
To improve the low observability of micro-satellites can effectively improve the using efficiency and survivability of micro-satellites, a static environment planning algorithm based on the sparse A * algorithm (SAS) is proposed. By adjusting attitude angles such as pitch angle, azimuth and roll angle of micro-satellites, the RCS value of micro-satellites in the direction of the threat radar can be effectively reduced, and the low observable characteristics of the micro-satellite can be improved. The simulation of the threat to microsatellites by the threat radars operating in the S-band and VHF bands shows that the low observability of the microsatellites is significantly improved after the planning and meets the requirements of flight attitude planning.
