It is desirable to separate and parameterize Rayleigh and Love wavefronts arriving at a three-component seismometer. We show that methods of modern array signal processing and parameter estimation will accomplish this task. An overall covariance matrix of vectors having elements representing the traces from each component of all seismometers yields the necessary information. We assume that the only vertical axis response is due to Rayleigh rv, and Love wave components Le and Ln appear only on east and north axes respectively.
