In this paper, we address the problem of direction of arrival (DOA) estimation for multiple targets in the presence of sensor failures in a sparse array.

In many scenarios, the number of defects that we are interested in is limited and the signaling response of the layered structure can be modeled as a low-rank structure.

Here, defects are inside a layered material structure, therefore, due to reflections from the surface of the layered material structure the defect detection is challenging.

Since the number of reflections coming from the MUT is limited, we propose sparse signal processing (SSP) to decompose the reflected signal.
