摘　　要：地形可视性分析是军事行动中的一项重要内容,近来,其应用已拓展到电信、旅游等领域中。围绕地形可视性建模、可视性计算及可视性应用等专题,对视线可视性和雷达可视性作了全面的论述,深入探讨了基于数字地面模型的视线剖面生成方法、可视判断算法、可视性结构以及可视性分析模式,最后总结了该领域最新的研究进展,提出了研究方向。Terrain visibility analysis is an important task in military operation, and now, it has been applied to the fields such as telecommunication and tourism. A survey was made for line-of-sight visibility and radar visibility which divided into three categories in terms of terrain visibility modeling, terrain visibility calculating and terrain visibility application, and a thorough discussion was given to methods for building line-of-sight profiles based on digital terrain model, algorithms for visibility judgment, visibility structures and analysis patterns. At last, the latest development in this field was summarized, and next study was put forward.
