New TDOA algorithm based on fuzzy BP neural network

A new TDOA algorithm based on FNN is proposed,in which the TDOA measurement is the input and the estimate value of target position is the output.Model structure of FNN is described,which is used for location.The recursive study algorithm for regulating parameters of FNN is obtained.In the end,the effect of the number of node in the input layer and the number of fuzzy If-then rule to the location precision is analyzed by simulation experiment,and the performance is also compared between algorithm proposed in this paper and CRLB.
