摘要
密集假目标干扰可以对雷达实施有效压制,使雷达无暇顾及真目标,甚至使雷达信号处理饱和。延时叠加法或卷积技术可以产生密集假信号,但它们会占用较多的资源。本文提出了一种新的密集假信号产生方法——分段重构法,该方法没有费时的乘法运算,占用的存储资源少,只与脉冲宽度有关,与假目标个数无关。仿真和试验验证了该方法的有效性。
Dense false-target jamming can implement effective blanket jamming on radar.This kind of jamming can make radar too busy to process true target,even bring on the saturation of radar signal processing.Time-delay and overlap-add techniques or convolution technique can produce dense false-signal,nevertheless they consume more resource.A new method for producing dense false-signal— compartmentalization and regroupment is proposed in the paper.This method does not include multiplication operation that needs more time and storage.It is related only to pulse width and has nothing to do with the number of false targets.Simulation and experiment results have proved the validity of this method.
