Abstract
A method for using an active sonar includes an acoustic antenna exhibiting a continuous bandwidth having a spectral emission width of at least two octaves and an electronic system for generating control signals for the acoustic antenna, the method comprising: dynamically selecting a plurality of distinct sonar functioning or operating modalities chosen from escort, surveillance, pursuit, dissuasion and communication, each using a different fraction of the emission bandwidth of the acoustic antenna, referred to as a channel; and using the electronic system to generate a plurality of control signals for the acoustic antenna corresponding to the selected functioning modalities, the electronic system being suitable for allowing the sonar to function according to a plurality of independent and simultaneous operating modalities. And sonar system for implementing such a method is also provided.
