Zusammenfassung:	ADAPTIVE CHANNEL FORMING PROCESSING FOR ACTIVE SONARThe subject of the invention is a method making it possible to form adaptive reception channels for a system comprising an antenna formed from a plurality of sensors.The method according to the invention consists firstly in grouping the sensors in a given arrangement, so as to construct N sub-antennas, the phase centers of which are separated from one another by a distance less than the correlation length of the noise, or of the nuisance channels. Each of the secondary channels, pointing in a direction m, is formed from the N primary reception channels pointing in this same direction m and formed for each of the N sub-antennas.Figure 111111111111111111111 III1671621111111111111*1-2.(11111(1121,
