本文提出一种基于模拟退火法的远场阵列误差有源校正方法,以解决水下多元线阵存在的阵列误差问题。此方法将分时工作校正源置于不同位置用于辅助校正,结合无条件最大似然方位估计算法构建目标函数,并利用模拟退火法进行阵列误差寻优。利用此方法进行性能仿真实验,结果表明:该方法校正精度高、鲁棒性好,具有较好的应用前景。
Aiming at the sensors errors of the underwater linear array with multiple sensors, a far-filed array calibration method with multiple sources is proposed.The method chooses a source working at different time and different place, then constructs objective function with unconditional maximum likelihood.Next, optimizing the sensors errors with the simulated annealing.Computer simulation is used for the mentioned method and the result show that the method has high accuracy, good robustness and great application prospect.
