Coprime sensor arrays with more than two subarrays
What is it about?
Coprime arrays until now have been composed of two uniform linear subarrays, each with inter-element spacings that are coprime multiples of the spatial Nyquist limit. Their upper-limit frequency and angular resolution scale with the product of these two coprime factors. By using three subarrays, another factor is introduced, which again multiplies the angular resolution and upper-limit frequency, further reducing the number of elements required to span a large aperture.
Why is it important?
Microphone arrays are useful for locating sound sources, as well as separating an acoustic signal from noise. Optimizing array geometries allows for less expensive and less complicated microphone arrays, which may make them more accessible for use in a wider range of applications.
