| 摘 要： | 双谱分析在雷达信号处理中已得到了应用,但未见在毫米波引信中应用,因此,提出将双谱分析法引入毫米波多普勒引信的目标检测中。该方法通过采用双谱及双谱对角切片进行毫米波回波信号的特征分析及特征提取,利用提取的特征进行有无目标的判别。试验表明:双谱分析用于毫米波多普勒引信对复杂背景中地面目标检测的识别率高于短时傅里叶变换(STFT)对信号的检测识别。

| Abstract: | Bispectrum analysis has been used in radar signal processing,but not in millimeter wave(MMW)fuze until now.A method of applying bispectrum analysis to MMW Doppler fuze target detection was put forward in this paper.Bispectrum analysis and diagonal slice of bispectrum were used to analyse the target's MMW echo and extract target's signatures,and whether the target existed was determined.Experimental results showed that bispectrum analysis applied in MMW Doppler fuze could promoted the recognition rate of gro... |
