首先建立了引信最佳起爆角模型及其误差分析模型;其次讨论和分析了影响起爆角散布的因素以及如何定量估计散布大小。其意义在于采用变换参数和求起爆角散布最大值法,简化了起爆角散布与模型输入参数之间的关系分析,对于引战系统的总体设计和引信利用制导信息进行最佳起爆角控制的误差分析具有实际意义。

Firstly, the optimal burst angle model and its error analysis model are set up in this paper; then the factors that affect the burst angle scatter and how to estimate the degree of scatter are discussed and analyzed. The method suggested in this paper adopts the transform parameters and the maximum value method for solving burst angle scatter, and the method can simplify analyzing the relation between burst angle scatter and model input parameters. It is of great significance for the fuze-warhead system design and for fuze to utilize the guidance information to make the error analysis for optimal burst angle control.
