According to the characteristic of cruise missile,this paper adopted third order combined altitude loop to restrain the radiation of altitude channel,and to eliminate the high frequency noise of baric-altimeter.
高度测量系统是影响巡航导弹巡航飞行、地形匹配、地形跟踪等过程的关键因素之一,文中针对巡航导弹的特点,采用气压/惯性三阶组合高度回路,有效抑制了高度通道的发散、消除了气压高度表的高频噪声影响,并针对组合高度回路的参数优化、动态性能等进行了研究。
To the advantages and disadvantages of inertial vertical channel,baro-altimeter and radar altimeter in height measurement system for cruise missile,based on the idea of combined altitude,Kalman filter is adopted to integrate these three altimeters,which can overcome the shortcomings while exerting the advantages of each.
针对惯性高度通道、气压高度表和雷达高度表在巡航导弹高度测量中的优缺点,根据组合高度的思想,采用卡尔曼滤波的信息融合技术,将三者有机地结合起来,取长补短,实现高度测量。
This article studies the problem of designing a seawave filter and a high integrative system for the helicopter skimming-over-the sea flight.
