基于RCS的风电机对高频雷达信号干扰特性分析
The Interference Characteristics of HF Radar Caused by Wind Turbine in Shortwave Frequency
摘要
Abstract
A wind turbine placed in the vicinity of the radar system would have a serious impact on positioning and tracking of the radar performance.In this paper the interference level wes evaluated on the basis of the HF radar work principle and used radar cross section(RCS).With actual HF radar work band (3～30 MHz) as example Hallen method was used to establish wire model of RCS calculating and the MoM was used to calculate the wind turbine far-field scattered field.Then the wind turbine model was established at different yaw angel and rotation angel and the corresponding wind turbine RCS was calculated,so as to get the interference characteristics of wind turbine.The results show that wind turbine RCS could be the parameter to evaluate interference level.The wind turbine RCS changes woldly at different yaw angel and rotation angel.When the HF radar frequency is 30 MHz,the maximum interference is 51.01 dBm2.关键词
