摘要 在介绍K-L变换压制噪声的理论依据基础上,通过建立理论模型进行试算研究和分析,得出必须注意的结果:K-L变换滤波有压制倾斜相干信号的作用。当特征值选取不当时,可能起模糊断层的作用。最后建议:对这种具有潜在的有可能危害有效信号的压噪技术,在工作中慎用或不用K-L变换。
Abstract :This paper deals with the theory in which the K-L transform suppresses the noise. Through research and analysis
of the theoretical model, the authors have reached the following conclusion: although the K-L transform filtering can
suppress the inclined coherent signal, it can also blur the fault signal if the characteristic value chosen is not
suitable. It is thus held that, as the noise-suppressing technology can destroy the effective signal, one must be careful
in using it or even should avoid using it in the work.
