Abstract
Systems and methods for virtually coupled resonators to determine an incidence angle of an acoustic wave are described herein. In one example, a system includes a processor and first and second transducers in communication with the processor. The first transducer produces a first signal in response to detecting an acoustic wave, while the second transducer produces a second signal in response to detecting the acoustic wave. The system may also include a memory in communication with the processor and having machine-readable instructions that cause the processor to modify the first signal and the second signal using a virtual resonator mapping function to generate a modified first signal and a modified second signal. The virtual resonator mapping function changes the first signal and the second signal to be representative of signals produced by transducers located within a hypothetical chamber of a hypothetical resonator.
