基于有源照射箔条云的速度欺骗干扰方法

Velocity Deception Jamming Based on Radiating on Chaff Clouds

提出了基于有源照射箔条云对雷达速度波门进行拖引干扰的复合干扰方法。该方法运用机载电子干扰设备接收、转发敌方雷达发射的信号并照射到箔条云上,箔条云对干扰信号二次辐射,被敌方雷达接收,形成具有和载机相似径向速度的假目标,起到诱骗干扰作用。建立了复合干扰对速度跟踪系统进行干扰的相关模型,并进行了仿真实验,仿真结果表明,利用该方法对敌机测速跟踪系统进行干扰具有可行性。

A new complex jamming method based on radiating on chaff clouds is proposed for jamming velocity gate walkoff of radar. First,the airbome electronic jamming equipment receives and transmits the radar signals launched by enemy radar and reflected by chaff cloud. Second, the chaff cloud irradiates the jamming signals and the signals are received by enemy radar. Finally, the false target with relativer radial velocity of the airborne is produced and the purpose of jamming is realized. The correlated model with complex jamming is established to validate this method. Experimental results show that the jamming strategy for the system of radar tracking system is feasible.
