摘要
为解决在多目标跟踪过程中,声纳存在交叉运动目标失跟问题.将多阵输出和多目标跟踪相结合,提出了基于概率数据联想滤波(PDAF)器的多阵多目标跟踪算法.计算机模拟结果表明,该算法在平面波模型下,利用两个线阵的输出可以稳定地跟踪两个交叉运动目标.将算法映射到DSP硬件平台,形成了一个多阵多目标跟踪的探测系统,实时处理的结果说明该算法对运动目标的估距误差小于5%
In the process of multiple target tracking,sonar usually loses track of cross-moving targets. With the advent of one submarine equiped with several hydrophone arrays,it was possible to combine multiple targets tracking with multiple array outputs. This paper proposes a tracking algorithm based on the probabilistic data association filter (PDAF). Using the model of plane wave incident to two linear arrays,the tracking of two cross-moving targets was studied through computer simulation. The simulation result showed that the algorithm is effective for reliably tracking two crossing targets. Mapping the algorithm onto a DSP hardware platform yielded a detection system with <5% error of range estimation.
