一种空管雷达风电场干扰抑制方法

风电场作为一种特殊的大型障碍物,具有复杂的电磁散射特性,会对空管雷达产生严重影响。针对空管雷达受风电场干扰的现实问题,本文提出了一种双波束并行处理抑制方法。首先依据风电场杂波和目标在高度和回波特征上的差异,结合空管雷达特点,构建了抑制系统的框架和流程;其次利用双波束的幅度和相位信息,设计了高度估计的方法;最后提出了杂波估计和抑制方法。实验仿真结果表明,该方法能够有效识别风电场干扰,提升空管雷达的抗风电场干扰能力。

A Method for Wind Farm Jamming Suppression in Air Traffic Control Radar

As a special kind of large obstacles, wind farm has complex electromagnetic scattering characte-ristics and can produce serious interference to air traffic control radar. Aiming at the realistic problem of air traffic control radar being interfered by wind farm, a dual-beam parallel processing suppression method is proposed in this paper. Firstly, according to the difference of clutter and target in height and echo characteristics and combining with ATC radar features, the framework and flow of suppression system are constructed. Secondly, using the amplitude and phase information of the double beams, the method of height estimation is designed. Finally, the clutter estimation and suppression are proposed. The experimental results show that the method can effectively identify wind interference and improve the anti-jamming ability of air traffic control radar.
