| 摘 要： | 飞行器在再入段的弹道可用较为精确的模型描述,利用UKF,分别结合动力学模型和＂当前＂统计模型,对再入弹道（弹道式和机动式）进行了估计,并就其滤波性能进行了对比分析.仿真结果表明,在对弹道式再入飞行器弹道的实时滤波中,BRV-Exp模型要比CS模型更为合适,弹道估计精度得到明显提高;在对机动式再入飞行器弹道的实时滤波中,MRV-Wiener模型并不优于CS模型.

| Abstract: | The trajectory of spacecraft in reentry phase can be described approximately by the model.The UKF is used to estimate the trajectory of ballistic reentry target and maneuvering reentry target in virtue of dynamic model and current statistical model,then the performance about the two models are compared.The simulation result shows that BRV-Exp model is more proper than CS model for the ballistic reentry trajectory and the estimation precision can be improved a lot,but the MRV-Wiener model is not excellent to... |
