针对多假目标欺骗干扰下的分布式组网雷达,提出了一种抗干扰的数据处理方法。该方法包括单雷达多目标跟踪-航迹关联检验-串行滤波融合3个步骤。首先各雷达分站独立进行多目标跟踪,获得各分站下真假目标对应的各个航迹。接着,对来自不同雷达的航迹进行关联检验,使真目标对应的航迹被保留,而假目标对应的航迹被拒绝。最后,在融合中心对通过关联检验的航迹进行融合,使对真目标的跟踪精度大大提高。仿真试验表明了该数据处理方法可使组网雷达有效剔除假目标,且更精确地跟踪真实目标。
Aimed at multi-fake target deceptive jamming distributed networked radar, an anti-jamming data processing method is proposed. The method includes three steps of single-radar multi-target tracking-track association verification-serial filtering fusion. First, each radar sub-station independent multi-target tracking, access to the sub-station under the true and false target corresponding to each track. Then, we test the tracks from different radars so that the tracks corresponding to the real targets are preserved, while the tracks corresponding to the false targets are rejected. Finally, the integration of the track through the correlation test fusion center, so that the true target tracking accuracy is greatly improved. Simulation results show that the proposed data processing method can effectively eliminate false targets and keep track of real targets more accurately.
