过去对歼击机火力控制系统误差分配方法,虽有一些资料,但缺乏系统化,且在误差综合上,从基础理论上看也存在着一些不正确的概念。本文根据对F_x火力控制系统的论证试验情况,提出以命中概率作为检验制订火力控制系统总误差的性能指标,推导出系统误差、随机误差对命中概率影响的公式,从而导出最佳限制系统误差的条件,在误差综合时,为纠正不正确的概念,得到总误差指标的高度可靠性、采用了置信限与置信度这两个指标。对纯追综型导弹火力控制系统的误差分配、也提出了方法与公式。通过对F_x火力控制系统的稳态误差的测试与空中试飞打靶的检验,看来方法是可行的。
In the past, some methods of error distribution for fighter fire control system were lack of systematization, and there were some incorrect concepts in the theory of error in terms of error synthesis. Based on the demonstration test of F_x firepower control system, this paper proposes to use hitting probability as the performance index to test the total error of firepower control system, deduce the influence of system error and random error on the probability of hitting, and derive the optimal system error Conditions, in the error synthesis, in order to correct the concept of incorrect, get the total reliability of the high reliability of the error, using the confidence and confidence of the two indicators. The method and formula for the error distribution of the pure chased missile fire control system are also proposed. Through the F_x fire control system, the steady-state error test and air test flight target test, it seems that the method is feasible.
