Long-Period Signal Separation. Large-Array Signal and Noise Analysis

Abstract : The problem of extracting the Rayleigh phase of an event of interest from a time-overlapping Rayleigh phase of another event was studied. Various configurations of the long-period LASA sensors and the following processing schemes were investigated: beamsteer processing using the great circle route and the dispersive curve velocity occurring at the peak power frequency; Wiener signal-extraction multichannel-filter processing; and a nonconventional adaptive filter processing scheme.
