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 ...

Prior knowledge-based direction of arrival estimation
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011 In a number of direction of arrival (DOA) estimation applications there exists prior knowledge about the sources whose bearings are to be determined. We study the case when this prior information concerns some of the source positions and their correlation state, which is a relevant case in, for example, RADAR scenarios where stationary objects exists ...
