Abstract. This paper is devoted to modeling of geophysical signals based on the parabolic spline function of local interpolation and processing of geophysical signals based on spectral analysis of signals. It is shown that the use of spline functions for constructing a mathematical model of digital processing and recovery of various geophysical signals is currently relevant for solving practical problems. The first experimental data of geophysical signals were taken as an example, and a parabolic local interpolation cubic spline model was constructed based on these data. Also presented is the process of interpolating the geophysical signal using the built-in local interpolation cubic spline model.
