| 摘 要： | 为了研究双基地声呐系统最优化配置问题,建立了双基地声呐系统优化配置模型。以优化配置模型为基础,通过计算定位精度的克拉美罗下界,得到了不同分置角状态下的双基地声呐定位精度,并且仿真分析了系统计时误差和测角误差对定位精度的影响。当以目标为圆心,收发声呐在相同的半径上布站时,定位精度的仿真实验结果表明,分置角为2π/3时系统定位精度最高,该研究对双/多基地声呐系统最优化配置具有一定的参考意义。

| Abstract: | In order to study the optimization configuration problem of bistatic sonar system,the optimal configuration model of bistatic sonar system was established.By calculating the Cramer Rao Lower Bound(CRLB) accuracy,the positioning accuracy of the bistatic sonar at different separation angles was obtained based on the optimized configuration model.And the effect of system timing error and angle measurement error on positioning accuracy is analyzed by simulation.When the target is the center of the circle and the transceiver sonar is deployed on the same radius,the simulation experiment results of positioning accuracy show that the system positioning accuracy is the highest at the separation angle of 2π/3,and this research has certain reference significance for the optimal configuration of bistatic/multistatic sonar system. |
