摘要
采用辅助声源法进行海底阵形估计,当远场条件不能很好满足时,采用平面波模型计算阵元位置误差较大。为此,提出一种可以有效地克服此类误差、明显提高测量精度的新方法。仿真和海底试验数据分析表明:该方法较传统的辅助声源法有较大改进,是一种工程上很实用的估计方法。
The performance of the existing array shape estimation methods, which utilize reference sources, will be degraded significantly when the plane wave assumption is not satisfied. In this paper, a new method is figured out, which treat this problem correctly and increase the precision obviously. The simulation and experiment data analysis showed that this proposed approach has better performance compared with the traditional method, and it is a practical method in realistic situation.
