摘　　要：In order to study the optimization configuration problem of bistatic sonar system,the optimal configuration model of bistatic sonar system was established.The positioning accuracy of the dual-base sonar at different dual-base angles was obtained by calculating the Cramér-Rao lower bound(CRLB)accuracy based on the optimal configuration model.The effect of system time measurement error and angle measurement error on positioning accuracy was analyzed by simulation.The transmitting and receiving sonar are deployed on the same circle centered on the target in the simulation.The results showed that the positioning accuracy was the highest at the bistatic angle of 2π/3.This research had certain reference for the optimal configuration of bistatic/multistatic sonar system.
