摘 要：該研究分析了國內(nèi)外各類無人機及其數(shù)據(jù)鏈，從眾多的無人機數(shù)據(jù)鏈測試科目中，篩選出作用距離、頻譜范圍、傳輸速率、誤碼率、傳輸延時等作為無人機數(shù)據(jù)鏈的通用測試項，給出了通用測試項的測試方法，為日后形成測試標準、規(guī)范奠定了基礎。通過分析、比較多種常用的評估模型，確定采用貝葉斯網(wǎng)絡作為無人機數(shù)據(jù)鏈的安全評估模型，并利用BayesiaLab軟件工具，實現(xiàn)模型的建立、分析和處理等功能。最后，嘗試建立一個無人機數(shù)據(jù)鏈貝葉斯網(wǎng)絡模型的實例。

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 UAVs 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 UAVs 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
