Abstract
The reflection characteristics of radar waves in coastal high-rise buildings form a certain shielding area, which makes it difficult for vessel traffic service to control the ship dynamic situation in sheltered waters. To study the overshadowing influence of coastal buildings on the vessel traffic service radar, an expression model of shielding area is established based on the structure characteristics of buildings and the relative height of radar. Then, the coordinate system is established, and the range and height of the shelter area are calculated, according to the geometric relation. Based on the theory of radar electromagnetic wave diffraction, the target height is calculated. Finally, taking the prince’s Bay Cruise Terminal Building on the radar Shekou radar as an example, the shielding area and height are calculated and visualized by the numerical calculation model and verified by real vessel test and observation. The building with a height of 60 m has covered 973,090 m2 of sheltered area for Shekou radar. The results can be used not only to analyze the influence of buildings on existing vessel traffic service radar stations but also to provide an important reference for site selection of vessel traffic service radar stations.
Highlights
Vessel traffic service (VTS) is a system based on traffic information to complete traffic control and to supervise the navigation dynamics of ships
To facilitate the analysis of simulation results, baffles perpendicular to datum plane are set in different positions within the scope of particle diffusion to intercept particles. (The attribute of particles is set as when transmitting along a straight line, the particles stay in the blocked position if encountered with base map, baffle, and building model.) The accuracy of the calculation results is verified through the analysis of the distribution and heights of intercepted particles
The points, whose spotting heights are zero, and the wharf shoreline are connected to obtain the boundary of shielding area with consideration of electromagnetic wave diffraction
Summary
Vessel traffic service (VTS) is a system based on traffic information to complete traffic control and to supervise the navigation dynamics of ships. (The attribute of particles is set as when transmitting along a straight line, the particles stay in the blocked position if encountered with base map, baffle, and building model.) The accuracy of the calculation results is verified through the analysis of the distribution and heights of intercepted particles. The high-rise buildings under planned construction will shelter the Shekou radar station, forming an infinite continuous 3D shielding area and a finite continuous 3D shielding area in the basin of Shekou port waters In this simulation, three baffles are set being flush with the embankment line, as shown, that is, Baffle A: A1–A2–A3–A4, Baffle B: B1–B2–B3–B4, and Baffle C: C1C2C3–C4–C5. The points, whose spotting heights are zero, and the wharf shoreline are connected to obtain the boundary of shielding area with consideration of electromagnetic wave diffraction. Shielding area and height: (a) geometric shielding height and (b) target spotting height
