摘　　要：为了提高计转数引信的定距精度,首次提出计转数分辨率的概念,根据实测的弹丸转数信号对每转周期进行分辨率提升,改善弹丸的空炸精度。该方法在不增加地磁传感器复杂度的前提下,通过改变计转数分辨率,结合递推法拟合出引信的计数脉冲。验证试验结果表明,根据实测的弹丸转数信号对每转周期进行分辨率提升,能够改善弹丸的空炸精度,从而提高计转数引信定距准确性。In order to improve the range accuracy of the revolution counting fuze,the concept of revolution counting resolution was proposed for the first time.The resolution of each revolution period was improved according to the measured projectile revolution signal to improve the air burst accuracy of the projectile.Without increasing the complexity of the geomagnetic sensor,this method could fit the counting pulse of the fuze by changing the resolution of the number of revolutions and combining with the recursive method.The verification test results showed that the air burst accuracy of the projectile could be improved by improving the resolution of each revolution based on the measured projectile revolution signal.The disclosure of this reason provided technical support for solving the problem that the accuracy of the fuze revolution count was not easy to improve and improving the accuracy of the fuze revolution count distance.
