摘要
为了有效解决机动目标自适应跟踪中系统误差的实时补偿问题,提出了一种基于修正输入估计的机动目标自适应跟踪与系统误差配准算法。该算法将目标机动加速度看作未知输入向量附加至状态方程,同时,将未知的系统误差向量附加至量测方程,推导出状态方程和量测方程扩维情况下目标滤波算法,在目标跟踪过程中实时估计机动加速度,并对系统误差进行配准。仿真结果表明,该算法可解决机动目标的自适应跟踪和系统误差实时修正问题。
To solve the real time compensation problems of the systematic errors during the adap tive tracking for the maneuvering target, an adaptive tracking and systematic error registration algorithm for the maneuvering target based on the modified input estimation is proposed. In the algorithm, the maneuvering acceleration of the target is appended to the state equation as an un known input vector. Meanwhile, the unknown systematic error vector is appended to the meas urement equation. The target filter algorithm for the augmented state and the augmented meas urement equations is exported. Then, the maneuvering acceleration is estimated in real time dur ing the target tracking, and the systematic error is registered. The simulation results show that the algorithm can solve the problem about the adaptive tracking and real time systematic error registration for the maneuvering target.
