| 摘 要： | 对天基红外卫星系统低轨部分(SBIRS-Low)单星只测角的主动段跟踪交接进行了研究。提出了用插值和滤波两种方法计算目标视线(LOS)偏差的算法。仿真讨论了多项式阶数和时间窗长度对插值外推法的影响,以及插值外推法与滤波法性能的比较。结果表明:当预测时间小于30 s时,预测视线偏差小于0.4°,此时预测视线将以较大概率落入跟踪相机视场角1°×3°范围内,满足主动段跟踪交接条件,表明单星主动段跟踪交接具可行性。

| Abstract: | The tracking and connecting of s aingle satellite in SBIRS-low were studied in the paper. A method of line of sight（LOS） bias was put forward. The influences of the polynomial order and time window length on the intersection extrapolation method and the comparison of the performances between the intersection extrapolation method and filtering method were discussed by the simulation. The results showed that the LOS error predicated was smaller than 0.4° for the predication time was less than 30 s, and the LOS would be fall into the tracking camera field 1°× 3° with large probability that the active tracking and connecting conditions were met. It showed that the active tracking and connecting of s single satellite was feasible. |
