To this paper we were carried tentatively on spectrum whitening in prestack, and each section after division scale is processed with spectrum whitening, particularly the composition of high frequency is raised apparently, the signal - noise ratio of high frequency raise. the resolution of whole section is better than stack
本文還嘗試性地在疊前進行譜白化處理，對分尺度后的各個記錄分別進行譜白化，尤其是高頻成分提高得很明顯，有效地提高了高頻信噪比，整個剖面的解析度明顯增強。The experiment results show that there are optimal defocus distance and exposure for the given system and recording material, and to obtain the best snr different reference - to - object beam ratios are also needed for black - white digital images of different space frequencies
實驗結果表明，對于給定的系統及記錄介質存在一定的最佳離焦量和曝光量，而對于不同空間頻率的黑白二值條紋圖像還需要採用不同參?物光比以最終獲得最佳的信噪比。We find that the noise level of the record is very low. even in weak ground motion condition the digital broad - band record has high signal - to - noise ratio when the period is as long as 20 sec. the signal - to - noise ratio of the velocity - type records is lower than that of the acceleration - type records
木義發現，數宇寬頻帶記錄的啪盧水平很低，在川朔k達205時，即仗在弱地震動的惰況下，還具有較高的信啪比，並且濁度型記錄的信噪比禾廠加讓度型門錄的信噪比。
