线性Radon变换在弱信号提取及强干扰噪声抑制的应用

The application of linear Radon transform in coherent noise elimination and weak signal extraction

介绍了线性 Radon变换方法 ,克服了二维滤波 ( F-K滤波 )由于空间假频现象严重 ,可使信号与噪声有效地分离。通过对合成信号和实际数据进行处理 ,信号的信噪比和分辨率有了明显的提高 。

The method of Linear Radon transform,which overcomes the shortage of serious spatial aliasing,can separate the signal and noise effectively.With experiment on theoretical and practical data,Linear Radon transform method is much better than F K filtering for linear noise suppression.Consequently the signal noise ratio (S/N) and resolution of data is highly improved.
