Classification: CPC H  G | IPC G  H

Claim 0:
1. A system for determining an incident angle of an acoustic wave, the system comprising:
N transducers that receive the acoustic wave, wherein N is a natural number greater than or equal to 2;
N coupled analog circuits that solve a set of N coupled differential equations modeling a set of N virtual coupled acoustic resonators, wherein each of the N coupled analog circuits receives an output signal from a unique one of the N transducers and outputs a voltage signal;
one or more processors; and
a memory communicably coupled to the one or more processors and storing a plurality of program instructions that when executed by the one or more processors cause the one or more processors to output an estimate of the incident angle of the acoustic wave based on an analysis of the N voltage signals output by the N coupled analog circuits.
