| 摘 要： | 分析了混合于地磁场的偶极子目标磁场难以分离,致使水下磁场定位方法存在目标磁场模值不易获得的难题,提出了基于2次测量载体潜深实现定位的方法,利用潜深直接获取载体相对于目标的垂向距离,理论推导和数值仿真结果表明该方法原则上具有较高的定位精度.分析了潜深及磁场梯度误差对定位精度的影响及定位误差同2次潜深差的关系;讨论了单次测...

| Abstract: | Handicap to acquire magnetic field magnitude in situation of underwater magnetic localization due to the difficulty of separating magnetic field of dipole target mixed with geomagnetic background field was analyzed.An underwater localization method based on double measurements of vehicle draft depth and target magnetic gradients at different depth places was put forward.In the localization method,the vertical displacement of relative to target could be directly obtained by its draft depths.Theoretical analy... |
