Abstract
An AD2CP includes at least one transducer assembly emitting sets of slanted directional acoustic beams and receiving the echoes; and electronics that processes the echoes into depth cells and computes velocity in each depth cell. The AD2CP is configured so that each beam set has a profiling catenation, at least two of which are different, and the AD2CP is configured so that the emitting, receiving and processing operate contemporaneously.
Claims38
An AD2CP, comprising:
- at least one transducer assembly emitting sets of slanted directional acoustic beams and receiving the echoes;
- and
- electronics that processes the echoes into depth cells and computes velocity in each depth cell;
- wherein the AD2CP is configured so that each beam set has a profiling catenation, at least two of which are different, and the AD2CP is configured so that the emitting, receiving and processing operate contemporaneously.
1 more element
An AD2CP, comprising:
- a first piston transducer assembly emitting a first set of slanted directional acoustic beams and receiving the echoes;
- a second piston transducer assembly emitting a second set of slanted directional acoustic beams and receiving the echoes;
- a single electronics that processes the echoes for both transducer assemblies into depth cells and computes velocity in each depth cell;
- wherein the first transducer assembly, the second transducer assembly and the electronics are integrated into a single package and the AD2CP is configured so that the emitting, receiving and processing operate contemporaneously.

An AD2CP, comprising:
- a first transducer assembly facing upward and emitting an upward set of slanted directional acoustic beams and receiving the echoes;
- a second transducer assembly facing downward and emitting a downward set of slanted directional acoustic beams and receiving the echoes;
- and
- electronics that process the echoes into depth cells and compute velocity in each depth cell;
- wherein the AD2CP is configured so that each beam set has a profiling catenation, at least two of which are different, and the AD2CP is configured so that the emitting, receiving and processing operate contemporaneously.

An AD2CP, comprising:
- a first transducer assembly emitting a first set of slanted directional acoustic beams and receiving the echoes,
- a second transducer assembly emitting a second set of horizontal directional acoustic beams and receiving the echoes;
- and
- electronics that processes the echoes from the slanted beams into depth cells, computes the velocity in each depth cell, and processes the echoes from the horizontal beams to compute velocity;
- wherein the AD2CP is configured so that each beam set has a profiling catenation, at least two of which are different, the AD2CP is configured so that the emitting, receiving and processing operate contemporaneously.
2 more elements
A method for measuring current velocities, comprising:
- generating at least two sets of slanted directional acoustic beams and receiving the echoes, wherein each beam set has its own profiling catenation, at least two of which are different;
- processing the echoes into depth cells and computing velocity for each depth cell;
- and
- wherein the generation, receiving and processing for the beam sets takes place contemporaneously.
