摘　　要：提出了一种基于弹载地磁传感器计转数引信自主初速测量、根据实时测量速度修正弹丸作用时间的定距弹系统工作方法,并对影响该系统定距精度的各误差源进行了定量分析,计算得某30弹丸1000 m定距精度为4.32 m。结合试验,证明基于地磁计转数测速定时修正技术可以实现较高的引信定距精度、有效提高弹药对目标的精确打击能力。An autonomous initial velocity measurement of counting revolution fuse based on geomagnetic sensor was proposed.A fixed distance system for correcting the initiation time of projectile in real time according to the initial velocity was proposed.The basic principle of measuring the initial velocity of rotation number was analyzed.A preliminary scheme of timing correction system for counting revolutions was put forward.The distance determination accuracy of the scheme was analyzed,it provides a theoretical basis for the study of turn count timing correction fuse.It is proved theoretically that the timing correction system of counting rotation is feasible.It can accurately realize the fixed distance initiation and improve the damage efficiency of the munition,and the design idea and method have certain reference significance.
