Abstract: The continual development of new concepts and techniques in the field of air traffic surveillance generates constantly more diversified demands for an accurate understanding of its operating mechanism. Security research, which deals with one of the fundamental issues of air traffic surveillance, emerges throughout the system at all levels, and provides important clues for exploring the emergence of air traffic surveillance system. However, there is as yet no widely accepted architecture for security research on air traffic surveillance up to now. Therefore, this article focuses on wireless communication technologies and security in air traffic surveillance system. In order to focus on the systems view, we divide all technologies used in air traffic communications into two categories according to their application: air traffic control and information services. Air traffic control are used to enable communication between controllers and pilots or their aircraft. Information services are technologies which provide information to pilots to improve their situational awareness. It also points out the future research and development trends in the field of air traffic surveillance and some key issues which remain to be solved.
Key words : air traffic surveillance;air traffic control,;information service,;wireless communication;security

    空管監(jiān)視系統(tǒng)被譽(yù)為空中交通管制員的“眼睛”,,主要是指檢測(cè),、識(shí)別和跟蹤目標(biāo)以及報(bào)告影響飛行安全的天氣現(xiàn)象??展茴I(lǐng)域的監(jiān)視手段種類繁多,,尤其是近年來(lái)隨著數(shù)據(jù)鏈及衛(wèi)星技術(shù)的發(fā)展以及飛行密度的增加,出現(xiàn)了多種空管監(jiān)視新技術(shù),,ADS-B,、ADS-C,、雷達(dá)、多點(diǎn)定位,、視頻監(jiān)控等技術(shù)共存,,每種監(jiān)視手段基于自身的技術(shù)特點(diǎn)都具有各自的適用范圍和監(jiān)視性能,為了最優(yōu)地利用各種空域監(jiān)視技術(shù),,實(shí)現(xiàn)飛機(jī)狀態(tài)的實(shí)時(shí)可信監(jiān)視,,基于多種手段的監(jiān)視技術(shù)開(kāi)始出現(xiàn)[1-6]

    信息安全一直是空管監(jiān)視系統(tǒng)中非常敏感和關(guān)鍵的問(wèn)題,。由于空管報(bào)文大多是開(kāi)放的數(shù)據(jù)格式,,信息無(wú)加密或加密算法過(guò)于簡(jiǎn)單,通信鏈路公開(kāi),、信息共享,,地面監(jiān)視設(shè)備與空域內(nèi)飛機(jī)之間以網(wǎng)狀和多點(diǎn)對(duì)多點(diǎn)的方式完成信息傳遞,不可避免面臨著安全性威脅[7-9],。
