摘要
宽带扫频式干扰是拦阻式干扰的一种,可在更宽的拦阻带宽内,实现更加均匀的干扰频谱.由于宽带扫频式干扰本身所具有的特性,目前常用的仿真方法很难对干扰信号的正确性及有效性进行验证.针对于此,提出了MATLAB仿真与FPGA实现相合的半实物仿真方法.利用此种方法对宽带扫频式干扰进行仿真及实现,可有效降低仿真结果验证的复杂性,不仅节省了仿真时间,而且充分利用了FPGA的高速、灵活、全数字结构和易移植等特点,使宽带扫频式干扰的FPGA实现具有更佳的可用性.
Frequency sweep jamming which is one type of the blocking jamming, has an even jumming spectrum in a wider bandwidth and is effective for all the signals in the bandwidth that you want to jam. It is very hard to verify the correctness and validity of feqeuency sweep jamming when using the usual simulation methods. For this, it is very helpful to use the halfobject simulation to verify the correctness and validity of frequency sweep jamming. And, the realization of broadband frequency sweep jamming is practicable.
