在海上反射剖面中,气枪气泡脉冲经常干涉表层反射。消除该效应的一般手段是在气枪附近安置一个传感器,以记录震源信号,然后用于产生反褶积因子。一种使用同态变换(非线性)将时间域的图件褶积变为频率域的相加的新技术,被用来获得震源信号估计值而无需记录震源子波。假定地壳有变化的地震响应,人们常将沿剖面的典型记
In the sea reflection profile, air-gun bubble pulses often interfere with surface reflections. The usual way to eliminate this effect is to place a sensor near the airgun to record the source signal and then use it to generate the deconvolution factor. A new technique that uses homomorphism (non-linearity) to transform the convolution of the time domain into the frequency domain is used to obtain the source signal estimate without having to record the source wavelet. Assuming that the earth’s crust has a varying seismic response, it is common practice to follow typical profiles along the section
