【摘要】：本文提出了基于光学散射特性的失稳空间目标旋转速率实验模拟方案以及数据处理方法,解决了失稳空间目标旋转速率反演的问题。实验构造了模拟真实光学观测的测试系统,使得卫星模型姿态、太阳方位、探测器观测角均与STK模拟场景相同,并模拟了低轨STSS卫星失稳条件下的探测过程,获取了多个周期的探测数据。通过频谱分析法、自相关法、交叉残差法处理实验数据,发现三种方法都可以成功反演出卫星模型的旋转速率,但交叉残差法受干扰较小,结果更准确。通过本文的工作,为今后通过光学散射特性反演真实卫星旋转速率提供了依据。
[Abstract]:In this paper, an experimental simulation scheme and data processing method for the rotation rate of unstable space targets based on optical scattering characteristics are proposed, which solves the problem of the rotation rate inversion of unstable space targets. A testing system for simulating real optical observation is constructed, which makes the satellite model attitude, solar azimuth and probe observation angle the same as the STK simulation scene, and simulates the detection process under the condition of the instability of the low-orbit STSS satellite. The detection data of multiple periods are obtained. By means of spectrum analysis, autocorrelation method and cross residuals method, it is found that all three methods can successfully reverse the rotation rate of satellite model, but the cross residual method has less interference and the results are more accurate. The work in this paper provides a basis for the inversion of the real satellite rotation rate by optical scattering characteristics in the future.
