FAST SINGLE-SNAPSHOT HARMONIC RECOVERY WITH 2D SPARSE ARRAYS USING BCCB MATRICES
ICASSP 2026poster
We introduce an efficient implementation of sparse recovery methods for the problem of harmonic estimation with 2D sparse arrays using a single snapshot. By imposing a uniformity constraint on the harmonic grids of the subdictionaries used in the sparse recovery problem, in addition to a mild constr…
