Patent ID: 8780672

Claim:
An acoustic Doppler system comprising: a plurality of acoustic transceivers; a first of the plurality of acoustic transceivers operating at a first acoustic frequency and being operatively connected to a first group of transducers producing an acoustic signal; a second of the plurality of acoustic transceivers operating at a second acoustic frequency and being operatively connected to a second group of transducers producing an acoustic signal; the first and second acoustic transceivers adapted to operate concurrently at the first and second acoustic frequencies; an acoustic subsystem controller operatively connected to the first and second acoustic transceivers, the acoustic subsystem controller controlling the acoustic signals produced by the first and second group of transducers; and a main processing unit operatively connected to the acoustic subsystem controller, the main processing unit being adapted to execute instructions to the first and second group of transducers to produce acoustic signals having at least two frequencies and being adapted to run at least two Doppler signal processing methods concurrently; the main processing unit analyzing data received by the first and second group of transducers, automatically adjusting the acoustic frequencies of the acoustic signals produced by the first and second group of transducers, and automatically selecting a method of processing the data received by the first and second group of transducers.
