针对人工免疫系统运用于电磁信号监测时,残留的噪声会引起较多系统虚警的问题,提出了一种适用于噪声环境下的电磁信号监测算法。算法借鉴免疫危险理论,通过采用＂危险区域＂对信号空间进行过滤,减少了突发噪声对系统的干扰。实际无线电监测数据实验表明,该算法能够显著降低系统虚警概率。
針對人工免疫繫統運用于電磁信號鑑測時,殘留的譟聲會引起較多繫統虛警的問題,提齣瞭一種適用于譟聲環境下的電磁信號鑑測算法。算法藉鑒免疫危險理論,通過採用＂危險區域＂對信號空間進行過濾,減少瞭突髮譟聲對繫統的榦擾。實際無線電鑑測數據實驗錶明,該算法能夠顯著降低繫統虛警概率。

When Artificial Immune System（AIS） is used in electromagnetism signal monitoring,there exists amount of false alarm of system due to remained noise,an electromagnetism signal monitoring algorithm applicable for noisy environment is presented in this paper.By introducing immune danger theory,the algorithm filters the noise from signal space with immune danger area,which can reduce the influence of remained noise.The model has been tested by real wireless signal monitoring data,and its results show that the algorithm can decrease the false-alarm probability apparently.
