仿真信号模糊一致性分析与风险评估方法

摘要

为了完善基于置信区间的仿真信号一致性分析方法,考虑了置信区间与接收区间的长度匹配问题,定义来最佳样本容量,并在此基础上提出了基于D-S证据理论的仿真信号模糊一致性分析方法.同时为了对信号仿真模型的风险进行定量评估,建立了信号仿真模型风险系数函数,得到多参数仿真信号风险系数向量,以此给决策者和/或仿真用户提供决策支持.最后,用水中兵器仿真试验中水中目标辐射噪声仿真的应用实例加以说明.%To perfect the method of confidence interval,the matching problem of the confidence interval of signal feature and the acceptance interval is discussed, and the best sample capacity is defined,then the method of fuzzy consistence analysis of the simulated signal based on the D-S theory is raised. Meanwhile, to assess the risk of the signal simulation to provide the decision-making supports for decision makers and/ or imitate customers, the risk coefficient function of signal simulation is established to obtain the risk coefficient vector of parameters. Finally, an example applied in the simulation of underwater target radiated-noise is taken into explanation.
