| 摘 要： | 研究表明风力发电场可能会影响航管雷达系统，导致其工作性能下降，因此准确评估风电场对航管雷达的影响具有重要意义。利用二次雷达信号特征给出了一种风电场对二次雷达影响的评估方法。首先根据二次雷达信号特征从风电场反射信号干扰方面分析了风电场对航管二次雷达可能产生的影响．然后阐述了以反射信号的时延来划分风电场影响区域的评估方法。最后通过在DEM（digital elevation model数字高程模型）数据上的仿真实验来验证本文评估方法。

| Abstract: | Research shows that wind farms may affect and degrade ATC radar systems. Assessing the impact accurately is one of the key issues to solve the problem. An impact assessing approach of wind farms is proposed on secondary surveillance based on signal characteristics. The impact of wind turbines is analyzed first based on the signal characteristics of secondary surveillance radar. Then the evaluation methods based on reflected signal delay is described. Finally, the method is verified through the simulation experiment based on DEM （digital elevation model） data. |
