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.
