| 摘 要： | 针对水下小平台难以实现低频近场目标定位的问题,研究了基于多个矢量水听器的协同定位算法。算法将多个矢量水听器视为不同的观测点,利用矢量水听器阵列流型特点估计出目标相对于不同观测点的方位角,根据这些方位角信息利用正交矢量算法对近场目标进行定位,避免了多维搜索过程,减少了计算量。仿真结果表明,算法能够准确地定位低频近场目标,有效地提高定位精度。

| Abstract: | Aiming at the problem of low frequency near-field target localization based on underwater small platform, this paper proposes a cooperative localization algorithm using multi-hydrophone. This method regards the sensors as different observers that estimate the azimuth of target respectively, and uses these azimuths to estimate the location based on orthogonal vector method. This algorithm avoids the search process, and reduces the calculation. The simulation results show that this algorithm can locate the near-field target accurately. |
