| 摘 要： | 风廓线雷达可为民航气象局、部队作战部署等军民活动提供高时空分辨率的大气风场信息，一般采用五波束进行探测，在探测过程中会受到来自自身和外界等多方面的信号干扰。为了研究抗干扰技术，介绍风廓线雷达的基本原理，对干扰的来源和措施进行分类讨论。分别从信号设计、频谱处理和波束控制3个典型角度进行抗干扰算法研究，并着重对本文提出的动态自适应波束选取(ADBS)算法进行介绍。仿真结果表明，本文算法对风廓线雷达抗干扰有效。

| Abstract: | Wind Profiler Radar(WPR) is widely applied to provide continuous atmosphere detection of wind field with high time-space resolution for airport, meteorological administration and army. Usually five beams are used for detection, and interference signals could exist because of different factors. This paper firstly introduces the fundamental principle of WPR. Then the resources of interference and countermeasures are discussed. Next, anti-interference algorithms in signal-design, data processing, and beam-control are discussed respectively. At last, an Adaptive Dynamic Beam Selection(ADBS) algorithm is proposed in detail. The simulation results show the effectiveness of this algorithm. |
