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