【摘要】 对用于小口径空炸引信的地磁测转数原理进行了论述 ,详细分析了地磁场的分布及特点和高度变化、地理位置变化、弹体本身的章动等因素对转数测量信号产生的不同程度的影响 ,并指出地磁场随地理位置分布差异很大是影响地磁法计弹丸转数的首要影响因素 ,最后介绍了测试地磁信号的方法并给出了实测地磁信号曲线更多还原

【Abstract】 In this article, earth magnetic method of recording the numbers of rotation applying to small caliber proximity fuze is discussed, the distributing and characteristics of earth magnetic field are analyzed, some effective factors to sensor’s output signal, such as variation of altitude, region are put forward, and it is pointed out that earth magnetic field’s notable difference on different regionis the main effective factor. At last, method of measuring the earth magnetic signal is introduced and result curves are given.更多还原
