Abstract
The application of superresolution techniques to circular arrays in mode space is proposed. This formulation allows the use of algorithms that are otherwise specific to equispaced linear arrays, with the added benefit of full 360° azimuth coverage. Coherent signals can be decorrelated by a mode-space version of the spatial smoothing technique, and, in the case of broadband signals, through an inherent property of direction-independent frequency-domain smoothing
