  • 摘要:

    为有效识别调频(FM)引信地面目标回波信号和数字射频存储(DRFM)转发式干扰信号,提出了一种对地调频引信粗糙面目标与干扰信号识别方法。建立了对地调频引信粗糙面差频信号模型,利用二维距离-速度提取方法提取其差频频率和多普勒频率,采用差频频率峰值带宽和多普勒频率峰值带宽2个特征量识别地面目标回波信号和DRFM转发式干扰信号,并使用蒙特卡罗仿真和非参数假设统计检验对其进行了验证。结果表明:差频频率峰值带宽和多普勒频率峰值带宽的展宽幅度与引信天线照射范围内粗糙面的大小呈正相关,多普勒频率峰值带宽的展宽与载频成正比,利用峰值带宽特性可有效区分粗糙面目标回波信号和DRFM转发式干扰信号。
