Side-lobe level reduction in bio-inspired optical phased-array antennas
(2017-11-27)
Phased arrays are expected to play a critical role in visible and infrared wireless systems. Their improved performance compared to single element antennas finds uses in communications, imaging, and sensing. However, ...
DOA Estimation using Random Linear Arrays via Compressive Sensing
(Institute of Electrical and Electronics Engineers, 2014-08)
In this article we analyze the performance of nonuniform linear arrays for Direction of Arrival (DOA) estimation. We use different classes of sparse recovery algorithms to estimate the direction of arrival of the signal ...
