Description: Description The MUSIC algorithm, proposed by Schmidt, first estimates a basis for the noise subspace and then determines the peaks the associated angles provide the DOA estimates.
The MATLAB code for the MUSIC algorithm is sampled by creating an array of steering vectors corresponding to the angles in the vector angles.

Description: 稳健自适应波束形成，Wiley出版社，是一本有关MVDR波束形成稳健性分析的好书。-The latest research and developments in robust adaptive beamforming Recent work has made great strides toward devising robust adaptive beamformers that vastly improve signal strength against background noise and directional interference. This dynamic technology has diverse applications, including radar, sonar, acoustics, astronomy, seismology, communications, and medical imaging. There are also exciting emerging applications such as smart antennas for wireless communications, handheld ultrasound imaging systems, and directional hearing aids. Robust Adaptive Beamforming compiles the theories and work of leading researchers investigating various approaches in one comprehensive volume. Unlike previous efforts, these pioneering studies are based on theories that use an uncertainty set of the array steering vector. The researchers define their theories, explain their methodologies, and present their conclusions. Methods presented include: Coupling the standard Capon beamformers with a spher

degraded .In this paper , in the view of the constraints on the weight vector and the uncertainty sets , we propose a new approach,
which is called Vector Optimization Robust Beamforming.It is shown that the proposed algorithm can be reformulated in a convex
form as the so-called Second-Order Cone (SOC)program and solved efficiently using the well-established optimization tool , sedumi.
