摘要
在拥挤的高频波段,高频地波雷达受短波电台的影响而不能正常地进行工作,空域波束形成和基于水平天线辅助旁瓣对消的干扰抑制方法被用来对消此类电台干扰。比较了基于不同辅助天线以及不同信号处理顺序情况下的干扰抑制性能,对实测数据处理结果表明,基于水平辅助天线的方法能够在保证目标信息不丢失的情况下抑制主瓣干扰,距离域旁瓣对消的方法表现出最佳的干扰抑制性能。
In the user-congested high frequency （HF） band, the HF surface wave radar can＇t work in gear due to the influence of radio interference. To cancel such interference, the spatial adaptive beamforming and sidelobe cancellation based on the horizontal auxiliary antennas are used in this paper. By comparing the interference cancellation performance of the methods based on the different auxiliary antennas and different processing order, the experiment results show that the sidelobe cancellation based on the horizontal auxiliary antennas can successfully reject the mainlobe interference without losing the target response, and the range domain sidelobe cancellation method exhibits the best performance of interference cancellation.
