Sensor array signal processing : two decades later
TL;DR: A brief review of the recent research activities in sensor array signal processing with a focus on estimation algorithms, which are classified into spectral-based and parametric methods depending on the way the estimates are computed.
Proceedings ArticleDOI
Direction-of-arrival estimation and detection using weighted subspace fitting
TL;DR: In this paper, a Gauss-Newlon type algorithm is proposed for minimizing the Weighted Subspace Fitti+ (WSF) criterion, and a new scheme is proposed.
Proceedings ArticleDOI
Reception of multiple co-channel digital signals using antenna arrays with applications to PCS
TL;DR: This work proposes a novel approach for separating multiple digital signals received at an antenna array that exploits the temporal structure of digital signals to simultaneously determine the array response and the symbol sequence for each signal.
Proceedings ArticleDOI
CLEAN technique in strip-map SAR for high-quality imaging
TL;DR: The CLEAN technique is extended to strip-map SAR system to produce high-quality images with a very good along-track resolution and the algorithm is applied to data from a ground-based circular SAR (CSAR) system to verify its implementation.
Proceedings ArticleDOI
On the resolution of The LASSO-based DOA estimation method
Ashkan Panahi,Mats Viberg +1 more
TL;DR: This paper investigates the consistency of the LASSO-based DOA estimation of the narrow-band signals in infinitely high SNR and shows that the resolution in infinitelyhigh SNR case for m sensors decreases by speed 1 over m.
