Bias Reduction for an Explicit Solution of Source Localization Using TDOA

  title={Bias Reduction for an Explicit Solution of Source Localization Using TDOA},
  author={K. C. Ho},
  journal={IEEE Transactions on Signal Processing},
This paper proposes two methods to reduce the bias of the well-known algebraic explicit solution (Chan and Ho, "A simple and efficient estimator for hyperbolic location," IEEE Trans. Signal Process., vol. 42, pp. 1905-1915, Aug. 1994) for source localization using TDOA. Bias of a source location estimate is significant when the measurement noise is large and the geolocation geometry is poor. Bias also dominates performance when multiple times of independent measurements are available such as in… CONTINUE READING
