摘　　要：针对海上风电场对岸基雷达探测威力的影响问题,基于实际拟建的海上风电项目和现役海军雷达装备,通过电磁仿真建模定量分析雷达天线辐射场及海上目标散射场通过风电场后,其分布特性受风电场的影响程度。分析结果表明,由于海上风电场的存在,风电场后端目标的回波功率较没有风电场时产生起伏,起伏程度与目标和风机的位置关系密切相关。To investigate the influence of offshore wind farm on the detection characteristics of shore-based radar,the electromagnetic scattering of wind farm on the sea is modelled in this paper,and then the radiation field distribution behind an actual wind farm is quantitatively studied.The results show that due to the existence of the offshore wind farm,the echo power of the target behind wind farm is more fluctuating than that in the absence of the wind farm.The degree of fluctuation is closely related to the position of the target and the wind turbine.
