Abstract：In ordinary denoise processing of suppressing linear interference,the denoise processing is often carried out for each computational range or sample,without considering whether the linear interference existing in that computational range or sample,resulting in loss of useful signal and influencing on denoise effect.Based on the method of suppressing linear interference presented by the reference [1] and the character that the correlation of linear interference in adjacent traces is stronger and the correlation of useful signal in adjacent traces is weaker,the paper presented the method of covariance measurement that judges whether there is linear interference in the computed sample or not.Based on the size of covariance value Cc computed in difference direction of some sample,the method judges whether the denoise processing should be carried out or not.The tests of model and practical data showed that adding this judging method can improve not only the hi-fi of signal,but also the denoise efficiency.
