摘　　要：提出了一种新的基于目标径向速度信息的多假设跟踪算法,来解决边搜索边跟踪雷达系统中数据互联问题,即在SB/MHT算法中,通过引入目标径向速度信息,构造新的航迹置信度公式,完善航迹启动条件。系统仿真结果证明,新算法可有效减少航迹数目,从而缩短系统计算时间,具有更强的抑制虚警的能力。A new multiple hypothesis tracking algorithm by using target Doppler information to solve the data association problem of modern radar systems is proposed in this paper.The novel feature of this method is that a new truth likelihood formula as well as initial conditions for new tracks is constructed by introducing target Doppler information.As numerical simulations indicated,the proposed method is effective,and can greatly reduce the number of tracks and computation time in comparison with the original one.
