对组网雷达的多目标航迹欺骗

Multi-target Track Deception Against Radar Net Working System

由于目前点迹压缩、点迹串行合并等融合方法在组网雷达中的普遍应用,使得对单部雷达的多目标航迹欺骗很容易被雷达组网系统所识别。为了能够有效地欺骗组网雷达,并在网内各雷达的PPI显示器上显示相似的航迹,在对单部雷达实施多目标航迹欺骗的理论基础上,提出了一种对组网雷达实施多目标航迹欺骗的方法。根据组网雷达系统中各雷达坐标位置的不同以及各雷达主波束对准干扰机时间的不同,详细讨论了产生具有空间相关性和时间相关性的可控欺骗航迹的算法。

The radar networking system can detect the false targets easily for the reason that the plot serial processing and other data fusion techniques are commonly used.In order to jam the networking system effectively,a method of multi-target track deception is advanced on the basis of that jamming against single radar.Considering the differences that between radars' position and the time that when the different radars' main lobe detecting the false targets in the radar networking system,the jamming technique's operational principle and algorithm are discussed in detail.And each track generated by the method is spatial correlated and temporal correlated with others.
