摘要
常规的ｆ－ｘ域预测滤波不仅理论上的假设比较苛刻，而且在分离随机噪音和有效信号时会引起信号畸变，降低输出剖面的保真效果和分辨率。本文对预测滤波器的各种误差来源和稳定性进行了分析，并提出了相应的改进措施。理论模型试算和实际资料处理结果表明，改进的ｆ－ｘ域预测滤波可以克服以上问题。
The conventional method of the f x prediction filtering is not only rigorous in principle, but also results in wavelet distortion and reduces the fidelity and resolution of the output section. In this paper, the authors analyze the error source and the stability of the filter and put forward the modified measures. The results show that the improving method can solve the problem successfully by processing the synthetic data and real data.
