摘　　要：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。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.
