Abstract

We introduce a numerical first-order derivative operator (gradient) that produces more accurate results than known traditional operators, such as Ando, Sobel and the so-called Isotropic operators. The derivation of the operator here draws from the concept of plane waves, a mathematical representation of wave propagation that is widely used in wave physics, and in particular, exploration seismology.
