摘　　要：为精细分析信号的能量聚集特性,提出了λ水平能量聚点的概念,其定义中的尺度因子d、水平因子λ分别具有调节信号分析的分辨率、灵敏度的作用。提出了一种基于能量聚点的信号特征分析方法,并应用于掩埋目标的信号检测。结果表明该方法有助于提高信号的检测率水平。To analyze the local condensation speciality of signal energy meticulously, the concept of energy condensation point on λ level of signal is presented. The scale factor d and level factor 2 in the definition of energy condensation point are used to regulate the precision and sensitivity of signal analysis, respectively. A method for analyzing signal feature is proposed based on the energy condensation point, and it is used in signal detection of buried target. The result shows that the method helps a lot for improving signal detection properties.
