摘要
当前,火星大气进入的初始状态不确定性和动力学参数不确定性已经成为制约火星进入制导技术发展的瓶颈,为进一步提高火星进入制导的精度,考虑不确定性的火星进入制导技术成为了近年来的研究热点。文章对火星进入制导技术发展的主要挑战和现有方法进行了梳理,对考虑不确定性的火星进入制导技术的改进发展现状进行了分类总结,并对存在的主要问题和可能的解决途径进行了分析和展望。
The initial state uncertainty and the dynamic parameter uncertainty of Mars atmospheric entry are the bottlenecks restricting the development of Mars entry guidance technique. In order to further improve the accuracy, Mars entry guidance technique considering the uncertainties has become a research hotspot in recent years. This paper sorts out the main challenges and existing methods of the development of Mars entry guidance firstly. Then, the improvement and the state-of-the-art of Mars entry guidance considering uncertainty are classified and summarized. Finally, the main open problems and potential solutions are analyzed and discussed.
