The analysis of three-dimensional shooting engine based on CADET

In this paper, a novel analytical method based on CADET (covariance analysis description equation technique) is proposed to solve the computing problem of the precision of the three-dimensional shooting engine when evaluating the effectiveness of the three-dimensional virtual shooting system. This method statistical linearizes the nonlinear factors that will affect shooting accuracy, and then get the propagation equation of mean and covariance. The simulation results show that compared with the Monte-Carlo method, and under conditions of the closely accuracy, computational complexity is greatly reduced with the method CADET, and the calculation results are more accurate.
