Abstract
A tetrahedral array is often used in acoustical sensing for its two-dimensional directivity despite its simplicity. What if a constituent sensor fails in the tetrahedral array? This work presents a lower bound of azimuth-elevation direction finding, when up to one of the array's constituent sensors fails but when the overall array remains functional.
