摘　　要：为了对信号仿真的决策分析进行研究,采用置信区间的方法分析信号特征参数的一致性。讨论了仿真输出抽样得到的参数置信区间与给定接收区间的长度匹配问题,完善了置信区间法;针对仿真一致性不够高的情况,建立了置信区间对于接收区间的偏离函数,提高信号仿真模型的调试效率,在此基础上提出了基于置信区间的信号仿真决策分析模型。最后,给出了该模型在武器装备水下航行体辐射噪声仿真模型中的应用实例。结果表明,该模型能充分挖掘仿真信号抽样所得到的有用信息,可为信号仿真建模VV＆A提供辅助决策,进而提高仿真置信度。To study the decision-making analysis of signal simulation,the method of the confidence interval is adopted to analyze the consistency of signal characteristic parameter.The matching problem of the confidence interval which comes from simulation sampling and the acceptance interval is discussed,which perfects the method of the confidence interval;Then,a deviated function is given about the confidence interval to the acceptance interval,which can increase the debugging efficiency of simulation model.Based on this,a decision-making analysis model of signal simulation based on the confidence interval is put forward.Finally,an example applied in the simulation of underwater target radiated-noise is taken into explanation.It illustrates that the model can scoop out a plentiful of useful information richly,which comes from simulation sampling and can provide auxiliary decision-making for the simulation model VVA and then increase the credibility of simulation.
