Abstract

A new method of target localization based on adaptive particle swarm optimization algorithm is proposed in view of the shortcoming of the existing localization algorithm and standard particle swarm optimizer algorithm

which has a complex calculation and is easy to be trapped in local optimum.The method has improved the inertia weight of the standard particle swarm optimizer algorithm

selected the particle swarm

and added adaptive mutation operation in iteration process to enhance its ability to break away from localoptimum

which the mutation probability is adaptively adjusted by variance of the populations fitness.The simulation results indicate that it could carry on the localization effectively through adopting the adaptive particle swarm optimization algorithm.when the variance of random noise interference is 0.5

the localization RMSE is below 0.8 m.
