本文提出采用希尔波特-黄变换（HHT）方法从干扰和噪声中提取微弱的冲击无线电信号。

The Hilbert-Huang Transform(HHT) methods is used to extract the weak impulse radio signal from interferential and noisy environment in this paper.

为了体现这一特点，本文将HHT进一步称为希尔·波特-黄变换局瞬信号分析(HHT - LISA)。

For showing this characteristic, this paper further calls the HHT as the Hilbert-Huang transform Local-instantaneous signal analysis (HHT-LISA).
