本文将一种新的求导方法应用于经典连续函数域内常规线性和双曲线τ-p变换,从而更有利于理解离散τ-p变换。为了滤除多次波等干扰波,导出τ-p变换的第一步是求其反变换,然后再计算正变换。做正变换时通常需要沿P方向做反褶积,以提高该方向的分辨率。在τ-p域内进一步改进同相轴分离技术则有助于滤波处理。对有限孔径数据而言,做线性及曲线
In this paper, a new derivation method is applied to the conventional linear and hyperbolic τ-p transform in the classical continuous function domain, which is more conducive to the understanding of discrete τ-p transform. In order to filter out the interference waves such as multiple waves, the first step of deriving the τ-p transform is to find the inverse transform and then to calculate the positive transform. When doing positive transformation, it is usually necessary to deconvolve along the P direction to improve the resolution of the direction. Further improvement of the technique of phase separation in the τ-p domain facilitates the filtering process. For limited aperture data, do linear and curve
