| Abstract: | A space location algorithm with linear least squares method for multistatic sonar is proposed by fusing the data of transmitters and receivers.Through numerical simulation,the effects of the system parameters on location accuracy are investigated.The simulation results show that the linear least squares(LLS) algorithm,taking full advantage of the system information,has higher localization accuracy in the whole domain than the method which simply uses three measurements to position the target in three-dimens... |
