  • 摘要: 针对脉冲型噪声,该文提出一种新的非线性处理方法,即高斯化-广义匹配(GGM)处理。GGM方法基于高斯化处理与广义匹配滤波,可结合非参数的概率密度估计进行设计,解决噪声模型未知时的非线性处理问题。该文以脉冲型噪声 ${\rm S\alpha S}$ 分布模型为例,分析GGM方法的特点和性能;再结合Class A噪声模型,讨论GGM设计作为非参数方法相比模型假设失配的优势;引入效能函数,验证GGM方法在恒虚警技术中的运用。结果表明,在已知噪声分布情况下,GGM方法具有次优检测性能;当噪声模型未知时,非参数GGM设计能保持稳健性能,优于模型失配下的处理。并且,GGM设计对样本数目要求不高,为噪声特性不明或时变的场景提供了一种新的信号处理方法。
