激光多普勒技术惯性导航系统组合导航高程计车载 laser Doppler technique inertial navigation system integrated navigation altimeter vehicle-mounted

摘要

为了给车式载体提供更准确的高程信息,提出了基于激光多普勒测速仪与惯性导航系统进行组合构建车载高程计的方案。利用激光多普勒测速仪与惯性导航系统分别测量车式载体的速度和姿态角,并结合初始点的高程解算得到待测点的高程。阐述了系统的结构和基本原理,并进行了车载实验。理论分析和实验结果表明：所设计的激光测速仪测量精度优于测量值的0.285%,将其与惯性导航系统进行组合测量某一地点高程信息是切实可行的。

Abstract

To provide accurate altitude information for vehicle carrier, a novel altimeter based on the laser Doppler velocimeter and the inertial navigation system is proposed. Laser Doppler velocimeter and the inertial navigation system are used to measure the velocity and attitude angle respectively. Combined the altitude of the origin, altitude data of the measured point can be acquired easily. The basic principle and structure of the altimeter are expounded and the vehicle-mounted experiment is carried out. Results of theory analysis and experiment show that the measurement accuracy of the designed LDV is better than 0. 285% and it is available to put this kind of LDV in use for vehicle-mounted altimeter.
