    无人机数据链测试与评估研讨作者: 李记辛 左新法 李现亭   摘 要:该研讨分析了国内外各类无人机及其数据链,从众多的无人机数据链测试科目中,筛选出作用距离、频谱范围、传输速率、误码率、传输延时等作为无人机数据链的通用测试项,给出了通用测试项的测试方法,为日后变成测试标准、规范奠定了基础。通过分析、对照多种常用的评估模型,确定选取贝叶斯网络作为无人机数据链的平安评估模型,并利用BayesiaLab软件工具,实现模型的建立、分析和处理等功能。最终,尝试建立一个无人机数据链贝叶斯网络模型的实例。

  Abstract: After analyzing many kinds of UAV and its DataLink worldwide,we select some items as DataLink common test items from numerous test items about UAV’s DataLink,such as operational ranges, spectrum, transmission speed, bit error ratio, delay and so on. Then we represent test methods about these items. In the future, we will publish UAV’s DataLink test standard basing on these test item and methods. Through analyzing and comparing a lot of current evaluation models, we think Bayesian Network is the best model for developing UAV DataLink safety evaluation mode. BaysiaLab is a good software tool. It can help you develop,analyze and hand your Bayesian Network. Finally, we attempt to develop a Bayesian Network sample of UAV DataLink.
  Key Words: UAV; Data link; Test; Evaluation; Bayesia network
