基于阵列的盲信号处理研究和应用OA北大核心CSCDCSTPCD
Research and Application of Blind Signal Processing Based on Array
本文对比了阵列信号处理与盲信号处理的数学模型,分析了二者的特点并进行了综合统一,提出了基于信号的非二阶特性空间扫描的概念,并验证了信号峰度随信噪比条件的变化和基于峰度的空间扫描.针对采用民用广播电台信号的外辐射源雷达所面临的严重同频干扰问题,采用独立成分分析的方法进行干扰抑制,并进行了实测数据的验证.
The model of array signal processing and that of blind signal processing are compared. Their characteristics are analyzed and unified. The concept of space scan based on non-second-order characteristics of signals is proposed. The kurtosis of signal changed with SNR and the space scan based on kurtosis are verified. According to the co-channel interference problem of the external illuminators-based radar using civilian broadcast signals, an independent compo…查看全部>>
