基于多传感器径向速度测量的目标跟踪方法

摘要

To solve the problem that the course estimation precision is low at the beginning phase and at time the target moving model is changing, a target tracking method based on multi-sensor radial velocity measurement is put forward. The method utilizes the high precision of radial velocity measurement of multi-radar and improves the precision of target moving parameter estimation with low-frequency and low-precision data. Theoretic analysis and simulation results show that the target moving parameter estimation precision is well improved by using the method put forward in this paper.%针对基于位置信息的目标跟踪在初始跟踪和运动模型变化阶段航向估计精度低的情况,利用传感器径向速度测量精度较高的特性,提出了一种基于多传感器径向速度测量的目标跟踪方法,以提高在数据更新频率和定位精度低的情况下的目标运动参数估计精度.理论分析和仿真实验证明了文中所提方法能较大地提高目标运动参数估计精度.
