摘要

摘要: 目前对线性调频(LFM)脉冲压缩雷达转发欺骗干扰主要通过移频调制转发和采样直接转发实现，常规转发干扰样式简单，干扰信号规律性强、复杂度低。该文提出一种基于间歇采样的多载波调制转发新型干扰样式。首先引用码片的概念对间歇采样过程重新建模，在此基础上，通过对当前采样码片附加不同移频量，结合多载波并行调制体制对其进行串并转换，利用不同次转发信号各子载波间的干扰累积，实现对LFM脉冲压缩雷达的数量、幅度、空间分布可控的逼真假目标干扰。仿真表明该干扰样式比移频干扰和直接转发干扰具有更好的干扰效果。

Abstract: Repeater deception jamming against Linear Frequency Modulated (LFM) pulse-compression radar is realized by frequency-shift repeater and direct repeater jamming so far. Conventional repeater jamming type is simple. Regularity of jamming signal is strong and complexity is low. A new repeater jamming type with multi-carrier modulation based on intermittent sampling is proposed. Firstly, the model of intermittent sampling is rebuilt with the code chip concept. Based on this, lifelike false targets with the quantity, amplitude and space distribution which can be controlled are produced by attaching different frequency-shift component to the present sampling code chip, deserializing signal used multi-carrier parallel modulation system and utilizing the accumulation of different times repeater signal jamming effect among sub-carriers. The simulation results show that the new jamming type has better performance than frequency-shift jamming and direct repeater jamming.
