| 摘 要： | 飞航导弹在外界导航系统不可用的情况下,可对航路上已知精确地理位置的典型地标进行测角和测距,从而实现对导弹导航位置误差的修正.飞航导弹为提高其隐蔽性,不能使用雷达或激光等有源测量设备,而采用成像观测又无法得到距离信息.因此为解决飞航导弹航路中隐蔽式导航自主修正的难题,提出了基于气压高度表的被动观测UKF滤波导航修正技术,从而实现飞航导弹在完全隐蔽情况下导航坐标的自主修正.

| Abstract: | When the other guidance system is not available,the cruise missile could measure the relative position with the earth-target which the geographical position and altitude is known.By using the outputs of the image leader and inertial navigation system,the missile could obtain its position and modify the error of inertial navigation system.Without the active measure instruments such as RADAR and LADAR,the passive observation leaders could not obtain the distance between targets and missiles.This paper present... |
