| 摘 要： | 被动声定位是智能地雷的关键技术之一，其中声传感器阵列测向确定了目标的方位角信息。通过Cramer—Rao下界分析了影响测向精度的因素，并将极大似然估计应用于智能地雷均匀圆阵的测向技术中，通过外场测试对坦克目标进行了相关的测向分析，结果表明精度满足智能地雷的系统要求。

| Abstract: | Passive acoustic DoA(Direction-of-Arrival)estimate using acoustic sensor array is a kind of key technology in intelligent mine system. The factors that influence the DoA estimate precision are analyzed through Cramer-Rao lower bound. The maximum-likelihood estimate is applied in DoA estimate using uniformly spaced circular array. Tank object DoA is then estimated by field test, and experimental results are analyzed. |

| Keywords: | intelligent mine DoA estimate maximum-likelihood uniformly spaced circular array |
