Efficient Closed-Form Estimators for Multistatic Sonar Localization

You are here

This paper addresses the multistatic sonar localization problem using the time measurements only or with bearings in the presence of Gaussian transmitter positions, receiver positions and propagation speed uncertainties. We develop efficient algebraic solutions to this nonlinear estimation problem
through parameter transformation and multi-stage processing. Both situations of known and unknown statistical distribution of the propagation speed are considered. Analysis supports their performance in reaching the hybrid CRLB over the small error region.
