摘　　要：为研究沿岸建筑物对雷达的遮蔽影响程度,根据建筑物的结构形式特点及其与雷达的相对高度建立遮蔽区域的表达模型;建立坐标系,根据几何关系计算得到遮蔽区范围和高度;基于雷达电磁波绕射理论,计算出遮蔽区的目标发现高度。以太子湾邮船母港建筑物对蛇口雷达的影响为例,运用数值计算模型对遮蔽区域的面积和高度进行计算及可视化,并用实船试验和实船观测加以验证。研究结果不仅可用于分析建筑物对现有VTS(Vessel Traffic Service,VTS)雷达站的影响,还可为拟建VTS雷达站选址提供参考。High-rise buildings along the coast may reflect radar waves and form a shadow area,which makes it difficult for VTS(Vessel Traffic Service,VTS)to monitor ships in certain sheltered waters.In order to study the influence of coastal buildings on VTS radar,a model of shadowing is established according to the structure characteristics of buildings and the relative height of radar.The coordinate system is set up,and the range and height of the shadow area are calculated according to the geometric relation.The diffraction of radar beam and the target height are taken into account.The influence of the Prince Bay Cruise Terminal Building on Shekou radar station is examined to verify the calculation.The results show that the calculation can make satisfactory prediction.
