This paper suggests using a tunable reflectarray as a hardware source of Sensing Functions (SFs) for Direction of Arrival (DoA) estimation based on Compressed Sensing (CS). Reflectarray is much more scalable than a conventional antenna array. This higher scalability can be exploited to build a measurement hardware with large aperture and high number of degrees of freedom. We introduce the simplified...
In many situations it is desirable to identify the direction of arrival (DoA) of an incoming signal. Recently the idea of compressive sensing have been applied to DoA problems using sub-sampled linear arrays of omnidirectional antennas. In this paper we explore DoA estimation with compressive sensing using antennas with diverse and reconfigurable patterns. Our results show that compressively-sampled...
