摘要
首先介绍了间歇采样转发干扰原理,指出了间歇采样转发干扰出现的假目标峰值位置,提出了一种基于间歇采样转发的脉间点积干扰方法,在对该方法进行数学建模后,分析了干扰信号时频特性;最后对基于间歇采样转发的脉间点积干扰进行了仿真,并将之与直接间歇采样转发干扰及增加了多普勒噪声调制间歇采样转发干扰进行对比。
First,the principle of interrupted-sampling repeater jamming(ISRJ)is analyzed,which contains the relative location of the false target of this jamming.Then,a new method of jamming,dot product jamming between pulses based on interrupted-sampling repeater is proposed.After the mathematical modeling of this method,the time-frequency characteristics of the jamming signal are analyzed.Finally,the dot product jamming between pulses based on interrupted-sampling repeater is simulated and compared with the interrupted-sampling repeater jamming and the interrupted-sampling repeater jamming with Doppler noise modulation added.
