对数据后处理雷达的分段卷积转发干扰研究

针对现有基于DRFM的移频干扰和分段转发干扰在对数据后处理雷达干扰时存在的不足问题,提出了一种新的分段卷积转发干扰方法。该干扰方法立足于干扰机天线收发分时体制,首先对接收到的雷达信号进行均匀分段、重新排序与噪声卷积后再进行转发。该干扰方法产生的假目标信号不仅能量大,覆盖广,而且假目标幅度差异明显,位置分布不均匀。最后的仿真结果验证了该方法的有效性。

Research on Technologies for Pulse Partition Convolution Repeater Jamming Against Data Post-processing Radar

As the existing frequency-shifting jamming and pulse partition repeater jamming based on DRFM are no longer effective in against data post-processing radar,a new pulse partition convolution repeater jamming is proposed in this paper. The jamming technique is established in jammer T-R separate antenna system,Firstly the received radar pulses are evenly separate,then the pulses in a rearranged order are retransmitted ,after they convolved with noise signal. This new method can generate macro-energy and broad coverage false targets,in addition,false targets have obvious difference in amplitude,and asymmetrical location. Finally,the simulation results prove the validity of the new jamming method.
