%X Using the time and frequency multi-resolution properties of wavelet transform,adaptive threshold adjustment method was designed.According to the different characteristics of signal and the random noise processed by wavelet transform in different scales,both rejecting true probability and false declaration probability were reduced.On the basis of reserving signal detail,the random noise was suppressed effectively.All the details were retained well.Peak error is from 0.7% to 1.0%,and peak position error is from 0.1% to 0.3%.And the analysis accuracy of spectrum signal and the precision of systematic decision pause were improved.
