| 中文摘要: |
| 在研究单枚主动定向浮标定位原理的基础上,推导出一种利用最小二乘法解算多枚浮标的定位结果的方法,并针对圆阵就阵元个数、圆阵半径以及测距误差对该解算方法的性能影响进行了数值仿真分析。仿真结果表明,该算法在测向均方误差较大或者目标在距离圆内的情况下,性能远优于单枚主动定向浮标;圆阵半径2 km左右,阵元个数在6左右时,该解算方法的性能达到最佳。此外,该解算算法很容易被扩展至三维定位问题,因此有一定的理论和应用价值。 |
| 英文摘要: |
| Based on the target location using a single active directional sonobuoy,a method to solve the target location of multi-sonobuoy using the mean square technique is derived.And the influence of parameters variations,such as sonobuoy numbers,radius and range error,on this method in a circular case is simulated.The simulation results indicate that this method is better than the single active directional sonobuoy when direction-finding error is relatively large or the target is in the circular.It is also indicated that when range is 2km and the number of sonobuoys are six,this method performs its best.Moreover,this method can be easily extended to the three-dimension case,which indicates that it has certain technical and practical significances. |
