利用数值微分技术描述机动目标的运动行为,建立了被跟踪目标运动参数的滤波模型和滤波-预报联合估计模型,可以在机动目标动态特性完全未知的情况下估计出位置、速度、加速度的当前值和一步预报值.这种方法建立的模型结构简单,而且容易根据各种应用要求构造合适的估计模型和选择估计算法,是一种鲁棒估计模型.仿真实验给出的结果显示这种模型对高动态目标能够获得良好的跟踪品质.
Using the numerical differential technique to describe the maneuvering behavior of the maneuvering target, the filter model of the tracking target’s motion parameters and the joint model of the filter-forecast are set up to estimate the current value of the position, velocity and acceleration when the maneuvering target’s dynamic characteristics are completely unknown And one-step forecasting value.The model established by this method is simple in structure and easy to construct a suitable estimation model and selection estimation algorithm according to various application requirements.It is a robust estimation model.The simulation results show that this model High dynamic goals can get good tracking quality.
