本文将作者在x—t域、τ—p域和f—k域中开发的基于波动方程的多次波压制滤波器,推广到了抛物线τ—p域。用多次波模型道(根据原始数据用波场外推法生成)与原始输入数据(多次波+一次波)进行能量对比,自动确定出多次波滤除区域。在抛物线τ—p In this paper, we extend the author’s multi-pass suppression filter based on wave equation developed in x-t domain, τ-p domain and f-k domain to the parabola τ-p domain. The multi-pass model is automatically compared to the original input data (multiple + primary) by using multiple model waveforms (based on the extrapolation of raw data by wavefield extrapolation) to automatically determine multiple filter regions. In the parabola τ-p
