Abstract

Abstract: In order to study the shielding influence of coastal building on the VTS radar, a mathematical expression model of shielding area is proposed. The expression model are divided into finite continuous 3D shielding area, infinite continuous 3D shielding area, finite discontinuous 3D shielding area and infinite discontinuous 3D shielding area. The range and height of the shielding area are calculated, according to the expression model and spatial geometric relation. In addition, 3ds MAX is used in the modeling and simulation of shielding area. Taking the influence of Prince's Bay Cruise Terminal Building on the radar Shekou radar as an example, the correctness and engineering practicability of the simulation method are verified by comparing the calculation results, simulation results and real ship test results of shielding area. The research can be used not only to assess the influence of buildings on existing VTS radar stations, but also can provide an important reference for supplementary regulatory measures of the maritime department and site selection of VTS radar stations.
