You have "deterministic" decon which take the horrible airgun signature and tries to make it shorter, more like a ricker wavelet.

Deconvolving a sampled signal?

I even saw a neat use of it when somebody made a digital violin. They needed the impulse response of the violin (an expensive one) and use a mechanical device to ping it. Unfortunately the device itself is not a pure impulse so its transfer function had to be separated from that of the violins using deconvolution.
