随着民航的发展，依靠管制员目视监视指挥的机场场面监视方式已不再适合航空安全的需要，而我国目前广泛使用的场监雷达系统成本较高、监视目标数量有限、恶劣天气条件下容易发生错误、并且存在一定的盲区。于是我国大型机场陆续引进全新的场面监视系统---多点定位（MLAT）场面监视系统。多点定位（MLAT）场面监视系统采用先进的技术，信息化的处理，实现机场的自动定位监视、智能引导、冲突告警，极大提高机场的安全性和运行效率。文章旨在从原理、构成、提高精度的方法及先进性等多个方面全面地分析多点定位（MLAT）场面监视系统，并对其应用前景进行了展望。%With the development of civil aviation, surveillance control way of the airport scene that relies on controllers visu-al monitoring is no longer suited to the needs of the aviation safety. And, there are many problems of high cost, limited number of surveillance targets, easily make mistakes in bad weather conditions and some blind spots. Just under such a background, large airports in China have introduced new scene monitoring system: multipoint orientation (MLAT) scene moni-toring system. The system is used advanced technologies and information processing to achieve automatic positioning monitor-ing, intelligent guide and conflict warning, which greatly improve the safety and efficiency of the airport. The article was roundly analyzed scene surveillance system of multipoint orientation from aspects of principle, structure, methods of improving precision and advancement. Finally, the paper was prospected application prospect of the system.
