摘要
压制式毫米波干扰模拟器能够真实模拟引信所面临的干扰环境,为实验提供阻塞噪声、瞄准噪声、扫频噪声。本文分析了压制式噪声产生原理,阻塞噪声、瞄准噪声采用噪声调频的方式得到,扫频噪声采用函数扫频的方式得到。提出了三种可行的毫米波干扰模拟器的实现方案:上变频方案、滤波方案和倍频方案。对以上三种方案进行了分析和比较,最终设计采用了倍频方案,并给出了实验结果。
The millimeter-wave blanket jamming simulator can provide the mm-band noise interference environment. It can provide mm-band barrage jamming and collimating jamming, and sweeping jamming. The generation principle of the blanket jamming is analyzed. Barrage jamming and collimating jamming are generated by the method of noise FM. Sweeping jamming is generated by the method of sweeping. Three realization methods of blanket jamming simulator are presented and analyzed： up frequency inverting method, filtering methods, frequency doubling. Final design used the frequency doubling method. The experimental results are presented.
