摘要
线性调频脉压雷达的军事应用日益广泛,因此对这类雷达的干扰问题已成为电子战的重要研究课题。本文基于线性调频脉压信号在时间和多卜勒频率间存在强耦合的事实,提出用移频干扰实现欺骗干扰的方法。文中讨论了干扰参数(J/S、频移速度)对干扰效果的影响,以及实现移频干扰的方法.对移频干扰引起的干扰信号压缩主峰的时间偏移进行了计算机模拟。移频干扰不仅有效地干扰线性调频脉压雷达,对相位编码雷达,干扰也十分有效。
Chirp radars have found ever wider military applications so that,electroniccountermeasure(ECM)of chirp radar becomes one of the important issues in electronicwarfare.Based on the fact that a chirp radar signal has a strong coupling between time and ve-locity,a deceptive jamming technique with shift frequency is proposed.The effect of thejammer parameter on jamming effectiveness and the generation technique of the shift fre-quency are discussed.The computer simulation of shift-frequency jamming has been done.The shift-frequency jamming is effective not only for chirp radars,but also for somephase-coded radars.
