数据融合技术在高度测量系统中的应用

飞行器针对不同的飞行高度采取了无线电高度和大气高度测量，两种高度在单独使用时存在很多不足之处。首先简要介绍了无线电高度和大气高度的测高原理，对比了两种不同测高原理的优劣；其次，介绍了数据融合的基本概念，并利用数据融合技术，从原理上对两种测高方法进行融合解算分析；最后，针对具体的项目，完成了数据融合技术在无线电高度和大气高度综合测量系统中的软硬件实现。

Application of Data Fusion Technology in Altitude Measurement System

Aircraft adopts radio altitude or atmospheric altitude measurement for different flight altitude, and the two measurement methods have some disadvantages when they are used separately. The paper introduces the measurement principle of radio altitude method and atmospheric attitude method in brief, comparing the advantages and disadvantages of the different methods. And then the paper describes the basic concepts of date fusion, and uses the data fusion theory to perform fusion computing analysis for the two measurement methods in principle. Finally, the implementation of data fusion technology in software and hardware in the radio altitude and atmospheric altitude integrated measurement system is described.
