METHOD OF USING A BROAD SPECTRAL BROADBAND ACTIVE SONAR AND SONAR SYSTEM

摘要

Method of using an active sonar (31) comprising an acoustic antenna (37) having a continuous passband having a spectral emission width of at least two octaves and an electronic system for generating signals for controlling said antenna acoustics (36), the method comprising: - dynamic selection of a plurality of distinct sonar operating or operating modes, each using a different fraction of the emission bandwidth of the acoustic antenna, called a channel; and the use of the electronic system to generate a plurality of control signals from said acoustic antenna corresponding to the selected operating modes, said electronic system being adapted to allow the sonar to operate according to a plurality of independent and simultaneous operating modes. And sonar system (31) for implementing such a method.
