Abstract:
For the purpose of localizing a distant noisy target, or inversely, calibrating the receiving array, the time delays defined by the propagation across the array of the target-generated signal wavefronts are to be estimated in the presence of array self-noise. The Cramer-Rao matrix bound is used to show that either properly filtered beamformers or properly filtered systems of multiplier correlators can be used to provide efficient estimates. The effect of suboptimally filtering the array outputs is discussed.
