   Abstract:
   The use of adaptive beamforming 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
