The nonlinear seismic reflection tomography problem consists on minimizing the function g(p)=||T−f(p)|| 22 , where p is a vector containing the velocity model parameters and depth position of the reflectors, T contains the travel time of the rays, and f(p) is a nonlinear function that depends on the velocity of the subsurfaces. Recently a new approach, based on the spectral gradient method,...
