WebThe concept of the convolutional model is important to understand the reflectivity of each trace in a 3D seismic volume. Mathematically, the convolutional model in the time domain is given by: x (t)=ω (t)*e (t)+n (t) (Yilmaz, 2001) Where: x (t) is the recorded seismogram. ω (t) is the seismic wavelet. e (t) is the earth’s impulse response ...

WebReflectivity is the capacity of an object to reflect solar radiation. It is described as a function of radiation wavelength and is determined by the physical composition of the object. The adjective “spectral” is frequently used in conjunction with reflectivity to indicate that reflectivity varies as a function of solar wavelength. Webearth reflectivity is a white sequence.
