在频率—空间域实现τ-P变换,优于时间—空间域或频率—波数域两类传统的τ-p变换方法。其关键在于不需要对原有序列进行重采样插值运算,因而比传统方法精确、快速。

To perform τ-p transform in frequency -space domain is believed to have more advantages over the two conventional methods of doing it in time-space domain or in wavenumber domain. What's considered critical is that there is no need in prat-ice to perform the calculation of resampled interpolation for the original sequence. So the method suggested could yield much faster and more accurate result as compared with the conventional ones. So long as you can pick out the number and steplength of the value P with reference to the basic criteria established and perform the least square inversion filtering,both alias effect and end effect could thus be negated. As a consequence.a most desirable outcome resulted from the transform could be produced.
