The problem of direction-of-arrival (DOA) estimation for sparse array is addressed. The perspective that DOA estimation in virtual array response model can be cast as the problem of sparse recovery is ...

In this work, we present an anti-interference direction of arrival (DoA) estimation system based on a space-time-modulated metasurface (STM-MTS). The proposed system, composed by a 1-bit STM-MTS and a ...
