| 摘 要： | 以对相位编码步进跳频雷达干扰为背景，分析了相位编码步进跳频信号和多载波相位编码信号的调制特点，在此基础上提出了一种多载波相位编码调制转发新型干扰样式，并理论分析了该干扰样式的干扰效果：可使相位编码步进跳频雷达产生多个导前、导后的逼真假目标.研究了等长度m序列的相关特性，给出了干扰信号的子载频和相位编码序列的选取准则.通过仿真实验对文中分析的结论进行了验证，结果表明该干扰样式较间歇采样预测转发干扰样式有较大的优越性.

| Abstract: | A jamming technique aiming at phase-coded stepped-frequency radar is proposed.The modulation characteristic of phase-coded stepped-frequency signal and multi-carrier phase-coded signal is analyzed.On the basis of the above,a new jamming technique of multi-carrier phase-coded repeater is presented.The new jamming effectiveness is analyzed theoretically.This method can make phase-coded stepped-frequency radar form several precede and lag lifelike false targets.The relativity of m series in equal length is studied.The opt principle of jamming signal sub-carrier and phase-coded series are presented.The conclusion is proved by simulation experiment.The studied result indicates that this jamming technique is superior to jamming technique of intermittent-sampling predictive repeater. |
