Abstract
The traditional marine designature process does not correct for far-field variations with the direction of propagation. We propose a simple and robust method to take this directivity into account. It is a trace-by-trace target-oriented technology which has the advantage of simultaneously respecting take-off and emergent angles, azimuth and receiver depth. A time variant application of this approach gives comparable results to a tau-p based correction valid at small azimuth only.
