Adaptive Beamforming using MUSIC Pseudo-Spectrum Figure 1: Conventional beamformers can use an array of sensors to estimate DOA Estimation of Direction of Arrival (DOA) is a vital task in many practical applications such as smart antennas, high-resolution radar, underwater acoustics, noise reduction, to mention a few.

Adaptive beamformers provides superior interference rejection compared to that offered by conventional beamformers. When the knowledge about the target direction is not accurate, the LCMV beamformer is preferable because it prevents signal self-nulling.
Mar 25, 2016 · Abstract: In this paper, we propose a novel adaptive beamforming algorithm for coprime array by compressive sensing the virtual uniform linear array signal. Based on the idea of coprime sampling, a much longer virtual uniform linear array can be generated from a coprime array.
