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.
