Frequency Estimation Using Minimum Norm Algorithm on Seismic Data

Abstract

Seismic signals are generally produced due to disturbances in the earth or an explosion that propagate through earth layers. The signal-to-noise ratio is very low for the generated signal. In order to increase its SNR and reduce the noise, various preprocessing techniques using FIR-based bandpass filter are considered. Minimum norm algorithm is implemented in the frequency domain to analyse the spectrum of the seismic signal in addition to analyse the tonals of the signal.
