In order to improve dynamic precision test and data processing of airborne anti-ship missile Fire Control System(FCS),we put forward a new analysis method for the FCS precision evaluation.By analyzing the FCS's dynamic precision test data,we built up the AR model for dynamic error sequence,and time serial discriminant function was introduced to evaluate the FCS precision.In test data modeling,the test data distribution was analyzed,the models of these data were set up respectively based on the hypothesis of Gaussian stationary process and non-Gaussian process.The two models had very different properties with latter's model parameters estimated by high-order cumulant.Compared with the classical test ruler,the method made the best of the reference system's data,and taking fully consideration of the distribution of the test data,so it would give more exact evaluation.
