Direct-Path Cancellation to FM Broadcast Transmitter Radar Based on Adaptive Fractional Delay Estimation

  • 摘要: 在连续波体制的双基地雷达中一个重要的问题是存在直达波干扰,传统的解决方法是通过自适应天线的干扰置零技术,但这对警戒雷达来说置零的深度有限。该文首先对基于FM广播辐射源的双基地雷达中的直达波干扰进行了分析;然后提出了基于自适应分数延迟估计直达波干扰抑制算法;最后给出了基于FM广播照射源的一个双基地实验系统,利用该实验系统采集的数据进行仿真,仿真结果验证了该方法的有效性。
