ABSTRACT:
The invention is a process relating to the processing of the signals sent by passive buoys dropped from an aircraft so as to compile EGP (Energy Geographic Plot) maps. The process is split into three steps: the first makes it possible to produce an EGP map of the x,y positions of the noise sources, the second makes it possible to associate the velocities Vx,Vywith certain designated positions and the third makes it possible to eliminate the noise sources regarded as hampering the readability of the maps.
