摘要

由于单帧相参积累在一些情况下存在较严重的信息损失，且这种损失会随着多帧非相参积累而进一步放大，使得传统动态规划检测前跟踪（DP-TBD）算法的性能下降.本文基于信息几何理论提出了一种矩阵DP-TBD算法，该方法直接利用每个分辨单元的协方差矩阵进行多帧积累，将单帧和多帧积累融为一体，避免了单帧积累存在的信息损失，具有更好的检测和跟踪性能.最后通过仿真实验验证了本文算法的有效性.

Abstract

The coherent accumulation in a single frame usually suffers serious information loss in some cases and it will be even worse through multi-frame incoherent accumulated

influencing the performance of DP-TBD algorithm.A new DP-TBD algorithm is proposed based on information geometry theory which uses the covariance matrix in every resolution cell to implement multi-frame accumulation directly

avoiding the information loss of coherent accumulation in a single frame with better detecting and tracking performance.Finally

the effectiveness of the proposed algorithm is verified by simulation test.
