| Abstract: | In this paper,the aerodynamic parameters of laser beem-rider guide anti-tank mis- siles are identified using maximum likelihood algorithms.In the course of iterative optimization of maximum likelihood algorithms,variable searching step is used to improve the identification criterion.As for a specific identification,the model decomposition is used, which considerably reduces the time of calculation and ensures the accuracy of the paramete.The estimated and simulated results are also given in this paper. |
