研究了多传感器多目标状态信息融合问题．针对被动式跟踪的特点，借助主动跟踪的距离通道值，提出类主动的被动式跟踪．在此基础上提出主被动串并联状态信息融合算法．仿真结果表明该融合方法可以大大提高跟踪精度，而且提高系统的可靠性 The multi-sensor multi-objective state information fusion problem is studied. Aiming at the characteristics of passive tracking, an active tracking is proposed based on the distance tracking value of active tracking. Based on this, the fusion algorithm of active and passive series-parallel state information is proposed. Simulation results show that the fusion method can greatly improve the tracking accuracy, but also improve the system reliability
