摘　　要：从决定射击平面内弹道特征的五个弹道诸元 ( υ、θ、x、y、t)入手 ,着重研究了火箭弹主动段末 K点弹道诸元的相对偏差与落点散布在射程方向的相对偏差之间的对应关系 ,定义并提出了弹道诸元对落点散布影响指数 ρ的概念及其计算方法 ,通过计算机仿真和对比分析 ,定量获得了对母弹引信开舱时间修正系统工作效能影响最大的弹道特征参数及其最低可接受的检测与解算精度。Starting from deciding the five trajectory data (υ，θ，x，y，t) of the interior ballistic trajectory features of a fire plane, this paper mainly studies the corresponding relation between the relative error of the trajectory data in point k of the active terminal of a rocket and the one of the impact point dispersion in the direction of firing range. The concept and calculating methods affecting index p are put forward in this paper. Finally, the trajectory feature parameters affecting the working efficiency of the ejection time-adaptive correction system of a dispenser fuze are obtained quantatively through computer emulatious and contrast analysis.
