摘要
为了满足智能地雷系统在雷场状况下应用的技术要求,利用单阵列小基阵有一定的定向精度但定距精度不高的特点,用三基阵中的2个方位角信息及阵列间的几何关系得出3个目标定位子解。再对3个目标定位子解采用方差加权融合处理方法,得到最终其定位解和方差。实验结果表明,利用三基阵进行声被动定位,能明显弥补单基阵定距精度不高的缺点,并能消除双基阵定位的盲区。算法简单有效,可应用于智能雷弹系统中,以提高其定位精度。
The multiple arrays location is an important aspect of the passive acoustic location. In view of the characters of the intelligent mine system, the paper derives the algorithm and the presentation based on the location of the individual array. The simulation shows that the precision of location from tri-array is superior to single array, and can also delete the blind band of the two arrays＇ location. This result can be directly used in intelligent mine system to improve its precision.
