SPIE - Education Introduction to Imaging with Sensor Arrays SC1244

The capture of data using an array of sensors is common in various wave propagation environments such as electromagnetic, underwater acoustics, ground surveillance, ultrasound and other modes. Images are generated by computational methods with such data using a variety of signal processing techniques. Applications encompass multiple areas such as millimeter and terahertz imaging, image synthesis from EM antennas, radar, sonar and acoustic imaging. This course will provide an introduction to the principles underlying methods of image synthesis from sensor arrays and applications in defense and security. Topics include: Sensor array configurations; far-field vs. near-field analysis, near-field focusing; array resolution and super-resolution; correlative interferometry; subspace methods; wideband processing; image reconstruction and synthetic aperture techniques; interference suppression and resolution enhancement algorithms; compressive sensing with sensor arrays; application to underwater acoustic arrays, synthetic aperture radar, phased array and smart antenna systems, target localization.
