Application of ARMA Model in Accuracy Analysis of Radar Dynamic Measurement

To solve the difficulty in the accuracy analysis of radar dynamic measurement, the mechanism and characteristics of dynamic measurement are analyzed, and the theory of random process is applied to dynamic test modeling and precision analysis. A radar dynamic test model based on auto-regressive and moving average process (ARMA) is built in the acceptance test of a certain type of radar. Based on the measured data, the test of model stability, model identification, model order, parameter estimation and model inspection are carried out, and the dynamic measurement precision analysis of a certain type of radar is completed. The application results show that the method proposed in this paper conforms to the dynamic test rule, and plays a role in radar accuracy analysis and measurement accuracy improvement.
