| 摘 要： | 将测船等效为一个磁偶极子,推导出测船磁化模型及船尾磁场强度的计算公式,提出了确定最佳拖曳距离的理论计算方法。实验结果表明,理论计算方法确定的最佳拖曳距离与传统的海上实验法确定的结果相差一般不超过1 m,验证了理论计算确定最佳拖曳距离方法的适用性。

| Abstract: | The determination of the optimum draggle distance between the sensor and the surveying boat is an important task in marine magnetic survey.It will greatly influence the surveying precision and working efficient.The surveying boat was seemed as a magnetic dipole in this paper,and the magnetization model of the boat and the formula that calculate the magnetic field strength behind it was deduced.The theoretical method which determine the optimum draggle distance was given out.The applicability of the method was validated with the practical test. |
