| 摘 要： | 测线间距设计是水下磁性目标探测的重要环节。把水下目标简化为磁偶极子，导出了更加合理的测线间距计算公式；为提高水下目标磁探测的可靠性与作业效率，分析了影响测线间距设计的各种因素，认为水下目标磁矩、海洋环境噪声水平和测点定位误差是测线间距设计中必须考虑的三个主要因素。

| Abstract: | Survey lines interval designing is the important key of underwater object＇ s magnetic detection. A formula about survey lines space is introduced by viewing the object as a magnetic dipole. In order to obtain more reasonable and reliable results, some marine magnetic detection factors that influence on the survey lines arrangement is analyzed. It is advised that the object＇ s magnetic moment, environmental noise and sensor＇ s positioning error are most important factors for survey lines interval designing. |

| Keywords: | marine magnetic detection survey lines arrangement environmental noise positioning error |
