摘　　要：为了实现自测速空炸引信的精确定距空炸,分析反比例修正、平均速度修正和一次函数修正3种常用自测速修正方法的修正误差。根据建立的弹丸弹道模型,利用MATLAB软件得到在不同初速条件下不同射程的飞行时间,并利用弹道解算结果与修正方法计算结果进行比较。仿真结果表明,反比例修正方法的误差最小,平均速度修正方法的误差最大,一次函数修正法的误差与射程基本呈线性关系。通过靶场试验,得到一次函数修正方法满足600 m定距误差小于8 m的精度要求。In order to achieve the accurate fixed distance air-burst of self-text air-bomb fuzes, an ana- lysis was conducted of the correction errors of three commonly used velocity correction methods, which were inverse radio correction, average speed correction and first function correction. According to the established ballistic trajectory model, the flight time of different ranges under different initial velocity conditions was obtained through the use of MATLAB software, and the results of trajectory calculation and correction methods were compared. The simulation results show that the inverse error correction method has the least error and that the average velocity correction method has the largest error. The er- ror of the first function correction method was linearly related to the range. Through the range test, it was found that the first function correction method could meet the accuracy requirement of 600 m distance error less than 8 m.
