摘要
随着现代雷达技术的发展,传统的单一假目标干扰及压制干扰的应用范围越来越有限,密集假目标干扰在电子对抗中应用越来越广泛,密集假目标通过产生大量虚假回波易引起虚假目标起始过多、目标错误跟踪等问题,会扰乱雷达对于真实目标的监视跟踪。基于对密集假目标干扰的产生机制的研究,提出了一种在数据处理层面,通过提前对干扰态势进行判别和感知的方法,对点迹是否为密集假干扰产生的数据进行判别,并通过分析其分布特性和回波特征信息,在航迹起始阶段,采用基于候选航迹径向速度的航迹起始抑制技术进行处理,在跟踪阶段,综合采用位置信息、点迹标注信息及特征信息进行多周期的航迹评判,有效减少了目标跟错的概率,并提高了关联准确性;最后通过实测数据对算法的有效性进行验证。
With the development of modern radar technology,the application scope of the traditional single false targets jamming and suppression jamming have becoming more and more limited,and dense false target jamming was finding wider and wider application in the electronic countermeasure.dense false target producing a large number of false echo was easy to cause false target initial error,false target tracking and so on,which would disrupt radar for monitoring of the real target tracking.Based on the research on the generation mechanism of dense false target interference,a method was proposed in the data processing level to distinguish whether the point trace was the data generated by dense false target interference discriminating and perceiving the interference situation in advance.And by analyzing its distribution characteristics and echo characteristic information,at the beginning stage of the track,the track initiation suppression technique based on the radial velocity of the candidate track was used to process the track.In the tracking stage,the location information,point trace labeling information and feature information were used to evaluate the track in multiple periods,which effectively reduced the probability of target tracking errors and improved the correlation accuracy.Finally,the effectiveness of the algorithm was verified by measured data.
