Operational combat-based artillery firing accuracy data analysis

In the test and evaluation of operation, the test benefits may be greatly reduced because no useful conclusions may be obtained from test data due to missing or incompleteness of test information records. Based on the characteristics of gun firing and by separating firing errors, this paper proposes an idea using for analyzing firing accuracy in case of incomplete test data records, establishes a method for analyzing chi-square distribution-based firing accuracy data, and conducts test data analysis on test data of a certain type of weapon. The effectiveness of this method is proven by analysis results which have offered effective method for conducting test data analysis.
