摘要
结合工程实践,设计和实现了一种变换域处理抗干扰算法,提出了一种对干扰谱线二次识别和二次置零的处理方法。该方法可降低算法处理信噪比损失,在干信比不小于60 dB时能降低4.5 dB。仿真分析和专用集成芯片实物测试证明了算法的有效性,在载噪比不大于60 dB时,由抗干扰算法引入的信噪比损失不大于2.5 dB。
According to engineering practice,an anti-jamming algorithm in transform domain is designed and implemented,and a method called“the second identifying and zero setting with the jamming spectral line”is proposed to reduce algorithm processing signal-to-noise ratio(SNR)loss.When jamming-to-signal ratio(JSR)≥60 dB,this method can reduce 4.5 dB SNR loss.Through simulation and the application specific integrated circuit(ASIC)testing,the effectiveness of the algorithm is demonstrated.When carrier-to-noise ratio≤60 dB,the imported SNR loss by the anti-jamming algorithm≤2.5 dB.
