深井探测仪的数据处理

研究了用功时谱使脉冲包络锐化的算法，噪声的产生，以及平方包络积累使弱回波信号得以检测的算法，使深井探测仪的测量精度得以明显提高，预估所需混凝土数量准确性提高，解决了探测到淤泥层时回波淹没在噪声中的问题。

Data Processing of Deep Well Detector

In order accuately to estimate the amount of cement,which is needed for the deep well piles poured in place, we must improve the measuring precision of deep well detectors. The problem which the returned wave signals are submerged in noise with the sitl seam of deep well being measured must be solved too.In this paper,the algorithm for sharpening pulse envelope using paver cepstrum and the algorithm for measuring the weak return wave singals using square envelope accumulation are presented.By use of the singal processing technique the measuring accuracy can be improved evidently.
