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 ...
