一种逐点处理的频域抗干扰新算法

Algorithm of Frequency Domain Anti-jamming by Point-by-point Processing

针对频域抗干扰算法不能抑制宽带干扰的不足,提出了一种逐点处理的频域抗干扰新算法。新算法先经过初始化检测块,然后以检测块来确定每个频点的干扰检测门限,而后对干扰进行处理。降低了干扰对门限确定时的影响,对单音干扰和部分宽带干扰具有较好的检测抑制作用,并通过仿真验证算法性能。

For the lack of wideband jamming inhibition of the frequency domain anti-jamming algorithm, a new point-by-point processing algorithm of frequency domain anti-jamming is proposed. The detection block is initialed by the jamming detection threshold of every frequency point, then they are determined by the detection block, followed by deal with jamming. This algorithm reduces the influence of certain threshold on jamming, which has bet- ter detective and inhibitive ability in single-tone jamming and part of wideband jamming and the performance is verified by simulation.
