摘　　要：机载预警雷达存在着固有的多普勒盲区问题,该盲区不仅易引起目标航迹中断和重起批,还容易引起数据关联的错误。基于此,提出了一种新的多目标点迹-航迹关联方法,该方法引入了由多普勒盲区造成的第二类空量测,将点迹-航迹关联作为最优二维分配问题求解,同时,为延长航迹寿命,采用多普勒盲区先验信息对传统航迹撤销准则进行了修正。仿真结果表明:在杂波、多目标环境且存在多普勒盲区的条件下,该方法航迹中断率较传统方法有明显下降。The airborne early warning radar has a natural Doppler blind zone(DBZ)problem.In target tracking,the DBZ can easily cause track termination and new initiation,and data association.because of this,a new multiple-target plot-track correlation method is proposed.In this method,the plot-track correlation is viewed as an optimization problem with the introduction of the second class‘dummy’measurement caused by DBZ,and the conventional method is improved by DBZ prior information for extension of track life.The simulation results show that this method has obvious descent of track termination rate compared with conventional methods in clutter environment,multiple-target environment and DBZ.
