摘　　要：该研究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,为日后形成测试标准、规范奠定了基础。通过分析、比较多种常用的评估模型,确定采用贝叶斯网络作为无人机数据链的安全评估模型,并利用Bayesia Lab软件工具,实现模型的建立、分析和处理等功能。最后,尝试建立一个无人机数据链贝叶斯网络模型的实例。After analyzing many kinds of UAV and its DataL ink worldwide,we select some items as DataL ink common test itemsfrom numerous test items about UAV＇s Data Link,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 Data Link 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 Data Link safety evaluation mode. Baysia Lab 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 DataL ink.
