Abstract

The invention discloses a maritime radar image simulation system for offshore wind farm waters. Its electronic chart analysis device is used to analyze and process the input electronic chart files to obtain the geography of land, sea surface, wind farm and water structures. information; the maritime radar attenuation simulator is used to simulate the geographical information of land, sea, wind farm and water structures to obtain the basic RCS map; the environmental additional loss simulator and the wind turbine additional loss simulator are used to simulate the environmental additional loss of the basic RCS map and The RCS map of the additional loss is obtained by the simulation processing of the additional loss of the fan, and the ship RCS simulator is used to process the RCS map of the additional loss to obtain the simulated RCS map of the maritime radar. This system can pre-evaluate the radar supervision and navigation safety conditions of relevant waters during wind farm planning and site selection, so as to provide data support for related work.

Description

technical field [0001] The invention relates to the technical field of maritime radar image simulation, in particular to a system and method for simulating a maritime radar image in the water area of ​​an offshore wind farm. Background technique [0002] In recent years, in order to alleviate the contradiction between economic development and environmental protection, more and more countries have begun to vigorously develop renewable energy. As one of the renewable energy sources with great potential, wind energy has the advantages of large total storage capacity, less environmental pollution, and large power generation, so it has been developed rapidly. Due to limited land resources, offshore wind power is stronger and lasts longer. Since the end of the last century, offshore wind power has developed rapidly. [0003] With the rapid development of offshore wind farms, wind turbines, as a large offshore obstacle, have gradually attracted people's attention to their adverse ...
