摘要
由于美国近些年来在临近空间高超声速飞行器领域给世界各国带来了巨大的安全威胁,它的高速和机动特性给地面防御系统带来了巨大的困难,引起了其他国家的广泛关注。在该领域的关键技术中,非弹道式机动跟踪滤波问题是尚未攻破的技术瓶颈。介绍了临近空间目标3种典型的非弹道式机动模式,并且从不同机动模式跟踪滤波方法、机动模式未知情况下的跟踪滤波方法、多种机动模式组合的跟踪滤波方法 3个方面进行了探讨,最后针对非弹道式跟踪滤波问题及应对措施进行了阐述。
Recently, America has successfully tested several flight vehicles flying in near space with high speed and maneuverability whic target with high speed is hard to be h brings great security threat to other countries. The maneuvering tracked by ground defense systems. Traditional filtering algorithms obviously cannot give accurate state estimation for such targets. Obviously, it will be a key technology to design accurate filtering algorithm for tracking such nonballistic near space targets in the future air defense systems. Four typical nonballistic maneuver modes of near space targets are proposed, and then the modes are discussed from three aspects including tracking filter ways of different maneuver modes, tracking filter ways of unknown maneuver modes, tracking filter ways of a combination of variety of maneuver modes. In the end the nonballistic tracking filter question and solutions are expounded.
