This approach exploits the fact that the number of microphones can be much larger than the order of the CDMA. As a result, the more microphones, th

In other words, a directivity pattern of order N can be obtained from the Jacobi-Anger expansion of order N, as long as this approximation holds. We also explain how to design circular differential arrays based on this approach and their relation

https://doi.org/10.1007/978-3-658-13219-4In general, a microphone array refers to a sound acquisition system that uses multiple microphones to sample the sound field with spatial diversity. These microphones are arranged into a particular geometry in which each sensor’s position relative to a reference point is known to the subsequent processors.
