Special emphasis is given to image generation. An overview of some important applications is provided, including sonar systems, medical ultrasound, and microphone arrays TEACHING METHODS Classroom lessons SYLLABUS/CONTENT Introduction to the array signal processing. Aims, methods, and applications. Acoustic signals. Basics of underwater acoustics and active sonar systems. Need for space-time processing. Data-independent array signal processing. Beamforming as a spatial filter. Linear and planar arrays. Beam pattern. Array gain and directivity index. Imaging-oriented digital beamforming: techniques and systems. Near-field and wide-band aspects. Beamforming implementations: time-domain and frequency-domain. 3-D imaging. Computational burden estimation.
