Method of Recognition of Target Height Based on Extended Kalman Filter

摘要: 目的研究现役红外制导反舰导弹对舰船目标高度的识别方法，从而为此类导弹的最佳命中点选择奠定基础。方法根据实际使用的导引头的技术条件，建立识别目标高度所需的数学模型，然后利用推广卡尔曼滤波理论识别目标高度。结果根据导引头的技术数据进行了大量的仿真试验，得到了目标高度的识别误差小于０．９ｍ的仿真结果。结论推广卡尔曼滤波识别目标高度的方法是选择最佳回调规律及确定最佳命中点的一种新方法。

Abstract: 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.
