A synthetic model with two layers: assume each layer is homogeneous. I try to use the depth-weighting function to counteract the decay. I think some data coresponding to the interface in the weighting file generated by depth-weighting function should be modified. what I think now is maybe the field reflection on the interface should be considered and the upper, lower bound?

Depending upon your geometry of ERT survey, you may need some depth-weighting. However, in most cases such as pole-dipole or dipole-dipole, we usually do not use depth-weighting, because data itself has sensitivity about depth, and inversion could resolve targets in different depths.
So, what kind of ERT survey are you trying?
Hi,
I am not entirely sure what you mean by reading your question. Would you like to fix the interface position at certain depth (as given by borehole by example) or to have a weighting function as a function of depth in the objective function in the entire model? On the decay, you mean the resolution/sensitivity decay with depth ?
