It is well known that the better part of the effect, on a seismic trace, of a near surface reflector can be eliminated by the application, on the said trace, of a linear operator of only 3 terms.

It will be shown that the effect of any number of such near‐surface reflectors can be eliminated, in the same way, with the aid of an operator of finite length and the means to construct these operators will be given.

In addition, the formulae used lead to an easy check of the fact that a seismic trace (completed by symmetry with respect to zero time) has to be an auto‐correlation function and allow the construction and the physical interpretation of a function whose autocorrelation gives the seismic trace made symmetrical.
