    Abstract:
    The use of adaptive beamforming prior to generalized correlation (GC) is demonstrated as a means of time-delay-estimate (TDE) bias reduction in interference-dominated environments. Analysis of GC TDE bias with both minimum-variance distortionless response and conventional delay-and-sum beamforming is given. At high interference-to-noise ratios, theoretical and simulation results indicate that the adaptive structure can facilitate improved delay estimation performance compared to conventional methods.
