文章[1]中,我们用明确的数字论证了使用均匀概率密度(线性概率分布)的噪音,只能在一个极窄的动态范围内使信号的真振幅得以恢复(即要求信噪比小于等于1)。这样的噪音显然对于动态范围高达120分贝的地震信号的真振幅恢复是无能为力的。本文的目的在于找到一个最佳的噪音函数以获得相应的最大的真振幅恢复能力。由此,也期望此项技术能够得到正确的评价,对它在应用上的局限性有一深入了解。
In [1], we demonstrate with clear numbers that noise using a uniform probability density (linear probability distribution) can only recover the true amplitude of a signal over a very narrow dynamic range (ie a signal to noise ratio of less than or equal to 1). Such noise is obviously powerless to true amplitude recovery of seismic signals with dynamic range up to 120 dB. The purpose of this paper is to find an optimal noise function to obtain the corresponding maximum true amplitude recovery. Therefore, it is also expected that this technology will be able to get the correct evaluation, its application in the limitations have a deep understanding.
