| Abstract: | To resolve the nonlinear optimization problem of TDOA Location,a hybrid method that employs a quantum genetic algorithm and a Chan algorithm were proposed.Individuals was updated by using binary-quantum-coding and quantum rotate gate,the optimal coordinate search was made.The simulation results show that the algorithm is steady and get the global optimal solution.It has a higher accuracy than the Chan algorithm and a faster convergence speed than the genetic algorithm. |
