摘 要：該研究分析了國(guó)內(nèi)外各類無(wú)人機(jī)及其數(shù)據(jù)鏈，從眾多的無(wú)人機(jī)數(shù)據(jù)鏈測(cè)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(shí)等作為無(wú)人機(jī)數(shù)據(jù)鏈的通用測(cè)試項(xiàng)，給出了通用測(cè)試項(xiàng)的測(cè)試方法，為日后形成測(cè)試標(biāo)準(zhǔn)、規(guī)范奠定了基礎(chǔ)。通過(guò)分析、比較多種常用的評(píng)估模型，確定采用貝葉斯網(wǎng)絡(luò)作為無(wú)人機(jī)數(shù)據(jù)鏈的安全評(píng)估模型，并利用BayesiaLab軟件工具，實(shí)現(xiàn)模型的建立、分析和處理等功能。最后，嘗試建立一個(gè)無(wú)人機(jī)數(shù)據(jù)鏈貝葉斯網(wǎng)絡(luò)模型的實(shí)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
