摘　　要：本文从信号高阶累积量的角度出发给出了一种基于地震信号双谱的高分辨率处理方法。该方法根据双谱的性质 ,首先从含有地震子波相位信息的地震记录双谱中精确地提取地震子波 ,然后进行子波处理 ,从而提高了地震记录的分辨率。理论计算表明 ,对不同性质的地震子波 ,均可从理论地震记录的双谱中重构子波。The paper gave a high resolution processing method based on double spectrum of seismic signal from angle of higher order accumulated amount of signal. Based on nature of double spectrum of seismic records containing phase information of seismic wavelet and afterwards conducts wavelet processing, the resolution of seismic records has been improved as a consequence. Theoretic calculation show that wavelet can be reconstruct from double spectrum of theoretical seismic data for seismic wavelet with different characters. Real data processing results also show that the method has an obvious effect.
