摘要 介绍了Hilbert-Huang变换中经验模式分解(EMD)的基本原理;讨论了实际探地雷达信号处理中EMD分解的终止条件;给出了利用内蕴模式函数(IMF)计算信号瞬时频率的计算公式。实际探地雷达剖面的HHT(Hilbert-Huang Transform)分析表明,由IMF得到的瞬时频率剖面对埋地目标的识别能力明显优于直接由探地雷达信号得到的瞬时频率剖面,并讨论了IMF的多分辨率特性。 The foundational theory about HHT(Hilbert-Huang Transform)based on EMD (empirical mode decom- position)is introduced in brief. The stop condition of EMD on the rear GPR data is discussed. The formula of cal- culating instantaneous frequency using IMF (intrinsic mode function)is presented. The identification of real buried object results shows that the IMF method is superior to the ordinary method. The multi-resolution of IMF is analyzed.
