Abstract

The paper deals with Doppler frequency extraction in foliage penetrating radar (FPR). The strong echoes from dense foliage and the high attenuation of the radar microwaves often make it difficult for traditional time-frequency distributions to represent the Doppler frequency clearly and locally. A Hilbert-Huang transform (HHT) technology is proposed to extract the desired signal from interference and to give a new Doppler frequency Hilbert spectrum. Higher signal-to-clutter ratio (SCR) and higher resolution in the time-frequency distribution are obtained.

基于Hilbert-Huang变换技术的叶突雷达多普勒频率提取

研究了叶突雷达(FPR)中多普勒频率提取问题。由于茂密植被的强回波和雷达微波的高衰减，使得传统时频分布难以清晰、局部地表示多普勒频率。提出了一种希尔伯特-黄变换(Hilbert- huang transform, HHT)技术，从干扰中提取所需信号，并给出新的希尔伯特多普勒频谱。获得了较高的信杂比和时频分布分辨率。
