摘　　要：Ｒａｄｏｎ变换利用信号的横向相关性和信号根幅随炮检距变化的特征，提取有效反射信号同相轴，同时提取的零炮检距地震剖面，保留了地震记录的高频信息，达到了提高分辨率的目的。叠前反Ｑ滤波是以ＦＵＴＴＥＲＭＡＮ衰减模型为理论基础，校正地震子波相位拉伸，补偿地震波频率和振幅的损失，达到提高地震资料分辨率和信噪比及改善同相轴连续性的目的。here are two purposes of Radon transform. One is the attenuation of noise,according to the lateral coherency of signal and the amplitude of signal yaring with offset,extracting events of effective reflection signal. The another is to increase resolution,by extracting zero-offset seismic section,which keeps high frequency content of seismic recording. Inverse Q filter be for stack is based on the attenuation model of Futterman. By correcting phase distortion of wavelet,compensating frequency and amplitude of seismic wave,the resolution of seismic data the signal to noise ratio are improved,and the events are more continuous.
