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。
The research analyzes various types of UAVs and their data links both at home and abroad and screened the range, spectrum range, transmission rate, bit error rate, transmission delay and so on of many unmanned aircraft data link test subjects as unmanned The common test items of machine data link provide the test methods of common test items, which lays the foundation for the formation of test standards and norms in the future. By analyzing and comparing many commonly used evaluation models, the Bayesian network is used as the security assessment model of UAV data link, and Bayesia Lab software tools are used to establish, analyze and process the model. Finally, try to build an example of a UAV Bayesian network model.
