目标的加速度估计在自适应目标跟踪算法中具有十分重要的作用。文中通过推导多普勒速度观测量和笛卡尔坐标系下加速度的关系,利用多个多普勒雷达的观测量,将目标的加速度估计转换为一个线性加权最小二乘问题。同理,此方法可以推广到目标速度估计问题中。通过仿真实验表明,文中方法能准确及时的估计出目标的加速度和速度。

Acceleration estimation plays an important role in the adaptive target tracking algorithm.In this paper,a relationship between measurements of Doppler velocity and the acceleration on Cartesian axis is derived.By utilizing the relationship equation and multiple Doppler measurements from different radars,acceleration estimation becomes a linearly weighted least squares problem.Similarly,the method can be extended to velocity estimation.Simulation results verify that the method in this paper can estimate acce...
