本文介绍了最近提出的使用传感器阵列输出的多目标角跟踪算法的改进方案。在保持原算法所有好的特点的同时,由于在更新目标角度估计中使用了递归近似,改进方案大大减少了误差的传播。常信号协方差矩阵的假设已不必要。通过涉及两个动目标跟踪的计算机仿真验证了所提出算法改进的性能。
This paper presents an improved scheme of the recently proposed multi-objective angular tracking algorithm using sensor array output. While maintaining all the good features of the original algorithm, the improved scheme greatly reduces the error propagation due to the recursive approximation used in updating the target angle estimation. The assumption of constant signal covariance matrix is not necessary. The performance of the proposed algorithm is verified by computer simulation involving two moving target tracking.
