Method of Recognition of Target Height Based on Extended Kalman Filter

Aim Studying the method of the infrared end guide anti ship missile to recognize the target height and select the best point of impact for this kind of missile. Methods According to the technical features, the mathematical model was founded and the extended Kalman filter was used to recognize the target height. Results From the simulation, the absolute error of the height is less than 0 9 m. Conclusion The extended Kalman filter is a new method to select the best reversing rule, i.e. to determine the best point of impact.
