摘要： An acoustic Doppler system comprising a plurality of acoustic transceivers, an acoustic subsystem controller and a main processing unit operatively connected to the acoustic subsystem controller. A first of the plurality of acoustic transceivers operates at a first acoustic frequency and is operatively connected to a first group of transducers producing an acoustic signal. A second of the plurality of acoustic transceivers operates at a second acoustic frequency and is operatively connected to a second group of transducers producing an acoustic signal. The first and second acoustic transceivers are adapted to operate concurrently at the first and second acoustic frequencies. The acoustic subsystem controller is operatively connected to the first and second acoustic transceivers and controls the acoustic signals produced by the first and second group of transducers. The main processing unit is adapted to execute instructions to the first and second group of transducers to produce acoustic signals having at least two frequencies and is adapted to run at least two processing methods concurrently. The main processing unit analyzes data received by the first and second group of transducers, automatically adjusts the acoustic frequencies of the acoustic signals produced by the first and second group of transducers, and automatically selects a method of processing the data received by the first and second group of transducers.
