摘要
针对线性调频雷达,基于信号间歇采样过程提出了一种周期交替采样建模方式。利用自主设置多组采样参数交替执行采样,可有效改善均匀采样有效假目标数量少、压制效果弱且规律性强的缺陷,并在间歇采样的基础上利用锯齿波卷积调制,产生灵巧干扰信号。经仿真验证,通过调整锯齿波的参数,能够产生灵活可控的假目标群,兼具欺骗和遮盖双重效果,具备独特的干扰优势。
A modeling mode of periodic alternating sampling based on signal intermittent sampling process is proposed for linear frequency modulation radar.That independently setting multiple sets of sampling parameters are used to perform sampling alternately can effectively improve the defects of uniform sampling such as few effective false targets,weak suppression effect and strong regularity.On the basis of intermittent sampling,sawtooth wave convolution modulation is used to generate smart jamming signals.Simulation results verify that a flexible and controllable false target group can be generated by adjusting the parameters of sawtooth wave,which has the dual effects of deception and masking,and has unique jamming advantages.
