To solve the issues of the defected theory basis and the distorted processing methods in dynamic accuracy test & evaluation fields for data processing of current shipboard artillery weapon system,one dynamic accuracy evaluation methodology for shipboard artillery weapon system based on timing series modeling theories is brought forward.Firstly,the current situation of the dynamic accuracy data processing methods in the shipboard artillery weapon systems is introduced,with corresponding problems discussed. The basic ideas of modeling and analyzing dynamic error series sampled from the shipboard artillery weapon system with timing series modeling theories are presented. On the basis of deeply researching on ARMA(Autoregressive moving average)/ARIMA(Autoregressive integrated moving average)modeling methods and ARCH(Autoregressive conditional heteroscedasticity)series modeling methods,the detailed algorithm of dynamic accuracy evaluation by ARIMA and GARCH(Generalized autoregressive conditional heteroscedasticity)ways is presented.Taking the data analysis and process on practical angular altitude dynamic error series of the shipboard artillery weapon system as an example,the detailed running procedures of using dynamic accuracy evaluation methodology for the shipboard artillery weapon system based on timing series modeling theories in the paper are presented.Comparison and analysis results on the model and practical data show that the approaches brought forward in the paper are feasible,and can be taken as an effective way to solve the corresponding issues in the dynamic accuracy test and evaluation fields of the shipboard artillery weapon systems.
