| 摘 要： | 建立合理水下小目标磁探测线间距需以定量分析各种因素对其影响为基础。将水下小目标的磁场模型视为磁偶极子,建立水下小目标的磁场空间衰减规律。根据水下目标磁探测的原理及其工作背景,对目标磁距大小、仪器信噪比、地磁变化、日变影响、测船的定位误差等因素进行综合分析,得出磁力仪在探测某一已知物时的测线间距计算公式。

| Abstract: | The analysis of the influencing factors constitutes the basis of designing the precise line interval in magnetic searching.Taking the underwater small object as a magnetic dipole,the authors found the law of the magnetic force attenuation of the magnetic object.A formula for defining searching line space was put forward based on an organic analysis of the influence caused by such factors as the magnetic force,signal-to-noise of the instrument,geomagnetic change,geomagnetic diurnal variation,and dynamic work... |
