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
The principle of geomagnetic rotation for small diameter air-blast fuze is discussed. The distribution and characteristics of geomagnetic field and height change, the change of geographical position and the nutation of the projectile itself are analyzed in detail. And pointed out that the distribution of geomagnetic field varies greatly with geography location is the primary influencing factor of geomagnetic statistic projectile revolution. At last, the method of testing geomagnetic signal is introduced and the measured geomagnetic signal curve
