径向速度量测在机动目标跟踪中的应用

Application of Radial Velocity Measurements in Tracking Maneuvering Target

针对机动目标跟踪问题,提出了一种引入径向速度量测的IMM滤波跟踪新方法。首先给出了观测数据的无偏坐标变换,由此得出位置坐标观测噪声的协方差矩阵。然后对引入径向速度量测的交互多模滤波跟踪算法进行了理论分析,最后进行了仿真实验。仿真结果表明,由于速度观测值提供了有关目标运动的更进一步的信息,从而使跟踪性能得到了较大的改善。

A new algorithm is presented to incorporate the radial velocity measurements into IMM filter for tracking maneuvering target. First, debiased coordinate conversion is given and covariance matrix of observation noise of position coordinates is received. Then IMM tracking algorithm using radial velocity measurements is analyzed in theory. Finally simulations are performed. The simulation results show that tracking performance can be greatly improved when the radial velocity is used.
