Beamforming and Direction of Arrival Estimation
The Phased Array System Toolbox™ includes narrowband and wideband digital beamforming algorithms. The algorithms cover spectral-based and covariance-based techniques. You can simulate phase-shift, Capon, minimum variance distortionless response (MVDR), and linearly constrained minimum variance (LCMV) of beamformers. In addition, the toolbox contains subspace-based direction-of-arrival estimation methods such as ESPRIT and MUSIC. System objects support target tracking using the 1-D and 2-D sum-difference monopulse trackers. You can employ techniques to suppress clutter and jammer interference using conventional or adaptive DPCA cancellers and sample-matrix inversion (SMI) beamformers. Many algorithms support both radar and sonar.
The toolbox provides narrowband and wideband beamformers, multiuser beamformers, hybrid beamformers, and conventional and adaptive beamformers. Implementations include delay-and-sum, Frost, generalized sidelobe cancellation, MVDR, and LCMV
