Here, a novel measurement matrix design methodology for CS based DoA estimation is proposed and its superior performance over alternative measurement matrix design methodologies is demonstrated. The proposed method uses prior probability distribution of the targets to improve performance. Compared to the state-of-the-art techniques, it is quantitatively demonstrated that the proposed measurement matrix design approach enables significant reduction in the number of analog channels to be processed and adapts to a priori information on the target scene.EnglishDirection of arrival estimationCompressed sensingMeasurement matrix designProceedings Paper10.23919/Eusipco47968.2020.9287679978-9-0827-9705-3
