Frequency-Diverse Computational Direction of Arrival Estimation Technique. [PDF]
Sci Rep, 2019 AbstractWe present a frequency-diverse based direction of arrival (DoA) estimation technique for millimetre-wave (mmW) 5G channel sounding. Frequency-diversity enables the creation of spatially incoherent radiation masks to encode the plane-wave signals incident on the radar aperture using a single antenna.

Deep Networks for Direction-of-Arrival Estimation in Low SNR [PDF]
IEEE Transactions on Signal Processing, 2020 In this work, we consider direction-of-arrival (DoA) estimation in the presence of extreme noise using Deep Learning (DL). In particular, we introduce a Convolutional Neural Network (CNN) that predicts angular directions using the sample covariance ...

Radar Antenna Selection for Direction-of-Arrival Estimations [PDF]
2021 IEEE Radar Conference (RadarConf21), 2021 Multi-antenna radars exhibit positively correlated detection performance with the number of elements utilized. The feasibility of refining antenna arrays to reduce cost of operation with only marginal loss of performance has attracted significant attention as utilizing a large number of elements may be prohibitively costly in terms of computation and ...
