Acoustic DoA Estimation by One Unsophisticated Sensor

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 10169)


We show how introducing known scattering can be used in direction of arrival estimation by a single sensor. We first present an analysis of the geometry of the underlying measurement space and show how it enables localizing white sources. Then, we extend the solution to more challenging non-white sources like speech by including a source model and considering convex relaxations with group sparsity penalties. We conclude with numerical simulations using an unsophisticated sensing device to validate the theory.
