SC1244: Introduction to Imaging with Sensor Arrays
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.
SC640: Introduction to Sensor Networks
Networks consisting of miniature sensors are an exciting new technological development made possible by advances in miniaturization, wireless systems and energy storage devices. Typical deployments consist of miniature battery-operated sensor nodes with wireless communication capabilities resulting in ad hoc configurations. They have a wide range of potential application in areas such as defense, homeland security, environmental monitoring and remote monitoring for plant safety. This course will provide a tutorial overview of sensor network systems covering various aspects such as collaborative processing, energy-aware routing, data aggregation and applications. Topics covered will include: sensor networks, basic frameworks for sensor network operation, energy and bandwidth constraints, reducing communication overhead through local processing, data aggregation: correlation strategies, distributed coding and compression, energy-aware sensor operations: routing and coverage, collaborative information processing, distributed computing paradigms, data and sensor fusion, and target/event detection.

The course deals with theory and application of continuous and discrete wavelet transforms. Topics covered include: time-frequency resolution, orthogonal and biorthogonal discrete wavelet transforms, multiresolution analysis, wavelet packets, wavelet design, implementation methods, image compression techniques and standards (JPEG2000), pattern recognition, watermarking for secure multimedia information dissemination and wavelet multitone modulation for high-speed internet access using ADSL technology.
SC901: Sensor Array Signal Processing
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. The processing of such sensor array data in space and time leads to meaningful information or output such as source localization, image reconstruction, range-velocity estimation, target identification etc. A variety of signal processing techniques have been developed since the early 1980s for achieving effective extraction of such information. New signal processing techniques are now being developed to handle emerging applications such as multi-input multi-output (MIMO) radar, millimeter wave imaging and Terahertz imaging.
