| 摘 要： | 本文从DRFM的时钟分析出发,研究了DRFM的A/D、D/A时钟差异对输出信号的影响,并以此为基础研究了DRFM输出信号对SAR进行干扰所带来的影响,研究了A/D、D/A时钟的差异与干扰模式和干扰效果的关系,最后通过仿真对前文的分析进行了验证。

| Abstract: | The clocks which control the DRFM 's A/D and D/A are analyzed,and it is proposed that changing the clocks' frequency of the A/D and D/A can change the DRFM's jamming types.It is also researched that the effects of the jamming signal from DRFM on the SAR jamming effectiveness,and it is concluded that the relationship of the frequency shifting of DRFM's clock to the cheating jamming effectiveness.The Matlab experimental results are given to illustrate the analysis. |
