警戒模式下多基地声纳配置方法研究

研究了警戒模式下多基地声纳的布阵方法。首先,利用双基地声纳"定位精度几何扩散因子"的几何分布图,提取图中定位误差满足要求的区域。然后,根据该区域的图形特征,提出一种基于正n边形作图方法的多基地声纳布阵算法。通过仿真分析可知,利用该算法布阵后,目标的定位性能与贪婪算法布阵后的定位性能基本接近,但是本文算法的运算量远比贪婪算法小,因此它具有更强的实用性。

A deployment algorithm of multistatic sonar for surveillance mode

A deployment algorithm of multistatic sonar for surveillance mode has been studied.At first,the area that the localization error is below the threshold was extracted from the GDOP(Geometrical Dilution of Precision) figure.Then,according to the shape of that area, a deployment algorithm based on regular polygons was put forward.The simulation result shows that the localization performance of this algorithm is similar to that of the greedy algorithm,but this algorithm is more practical for the computational loads are small.
