摘　　要：桥梁的建设将遮挡雷达站微波信号的传输,在大桥附近水域将会形成一定的雷达盲区,导致VTS中心无法掌握该水域的水上交通动态,不能对水上船舶现场进行连续跟踪,也不能对该水域进行有效的监控与指挥,给船舶通航带来了安全隐患。因此,应了解桥梁建设对VTS雷达站的影响,注意桥区监管设施的改善。文中结合悬索桥特点,应用建立的数学模型计算分析悬索桥对VTS雷达信号遮挡的盲区范围,为船舶监控及桥区通航安全提供技术支撑。The bridge will block the transmission of the microwave signal which comes from the radar station,the formation of certain radar near the bridge will be unable to be grasped by the VTS center, and VTS center cannot continuously track ships on the water scene or monitor ships effectively,which bring safe trouble to ships.Therefore,the impact of bridge construction on VTS radar station and the facility improvement of bridge district supervision should be understood.Combining with the charac-teristics of suspension bridge and the created mathematical model,the blind area of VTS radar signal being sheltered by suspension bridge is calculated and analyzed.It will provide the technical support for the navigation safety and the ship monitoring.
