基于运动特征的机载雷达目标断续量测处理

机载预警雷达对目标的量测经常出现断续现象,影响了航迹连续性要求。通过对机载脉冲多普勒雷达量测出现断续的机理分析,考虑目标进入雷达多普勒盲区的情况,基于目标运动特征提出利用联合关联波门与盲区预测相结合的处理方法,将重新出现的目标点迹与原有航迹进行关联,避免同一目标航迹因量测断续而重复起始。仿真结果表明了该方法的有效性与可行性。

Processing of Airborne Radar Target Discontinuous Measurements Based on Dynamic Character

The target measurements from airborne early warning radar are usually discontinuous,and the track continuity performance is affected.The discontinuous measurements of the airborne PD radar are analyzed and the target in the Doppler blind zone is considered,a method is proposed to associate the reappeared association measurement with the previous track on the basis of target dynamic character.The prediction with the Doppler blind zone and the integrated correlation region are combined to avoid re-initiation ...
