摘要
对概率数据关联滤波(probabilitydataassociationfilter,PDA)算法进行了改进.新算法考虑了临近目标对航迹更新的影响,修正了关联门相交区域内回波来自被跟踪目标的后验概率.仿真证明,新算法在计算量和PDA算法接近的情况下减少了误跟踪和目标丢失现象.
Probability data association （PDA） filter algorithm is improved. In the new algorithm,influence of neighboring targets is analyzed and the probability of public measurement in the intersection of validation gates from the tracked objects modified. Simulation results show that compared with the PDA algorithm, the new algorithm uses almost the same time but remarkably reduces tracking mistakes and the loss of objects.
