2) weak signal extraction
弱信号提取
1.
Subsection signals phase matching from single antenna,an improved weak signal extraction model has proposed based on the signal phase matching principle in electronic worfare envhronment in this paper,which aimed at that it\'s extremely difficult to detect and extract the pulse compression radar signal in low SNR at present.
针对目前电子战中脉压雷达信号淹没在强背景噪声中难以检测提取的现象,在信号相位匹配原理基础上,提出一种改进的弱信号提取模型—单元阵分段信号匹配法来实现对弱信号的提取;在此基础上结合多项式相位信号特点,提出一种改进的特征识别模型——剔除野点的多级中心差分法来实现对脉压雷达信号的特征识别。
