The Research of Fusion of TOA/TDOA Based on Particle Filter

The measurement information of TOA and TDOA is fused using the detection probability model by calculating the likelihood.In order to improve the accuracy in signal critical fields,a nonlinear target measurement information fusion algorithm based on particle filter is established within Bayesian framework to estimate the target in positioning.Simulation results shows that such algorithm gives a more efficient performance to compare to the situation of using single measurement information.
