中文摘要：

为解决机动目标参数辨识模型工程应用问题。采用扩张状态观测器等先进的非线性滤波算法，从实测的含有观测噪声的目标位置数据的序列中，直接估计出机动目标运动的一阶、二阶、三阶导数。并结合目标运动模型辨识的理论算法，在工程应用上首次实现了机动目标运动模态和运动模型的双重动态辨识，完成了目标模型动态辨识的工程化设计。

英文摘要：

Using the extended states observer, with this advanced nonlinear filtering arithmetic, can direct estimate first-order, second-order and third-order differential coefficient of movement of movable target from the measured target position information with strong noise. Based on this algorithm and other algorithms of movable target model, implemented dynamic recognition of movement mode and movable target model in engineering design.
