| 摘 要： | 在雷达目标跟踪中 ,扩展卡尔曼滤波 (EKF)和转换坐标卡尔曼滤波 (CMKF)得到了广泛的应用。但当目标方位角的测量误差与目标斜距的乘积较大时 ,传统的EKF和CMKF的滤波性能会大大降低。推导了有测速元时的去偏转换卡尔曼滤波 (DCMKF)算法 ,仿真结果表明DCMKF的精度比EKF与CMKF有了很大的提高

| Abstract: | Extended Kalman Filter(EKF) and converted measurement Kalman Filter(CMKF) have been widely used in radar target tracking. However ,when cross range measurement errors of target position are serious, the performance of conventional EKF and CMKF degrades considerably. In this article debiased converted measurement Kalman Filter(DCMKF) is inferred with velocity measurement. Simulation results show that DCMKF has a higher accuracy than EKF and CMKF. |
