EC4940: Mobile Ad Hoc Wireless Networking (3-2)

Instructor: M. Tummala

The course presents the fundamental principles, design issues, performance analysis, and military applications of infrastructure and ad hoc wireless packet switched networks. Radio wave propagation, wireless channel characteristic, orthogonal frequency division multiplexing, transceiver design, channel coding, and other physical layer technologies are reviewed. Principles of wireless local area and wide area (cellular) networks are presented. Design and performance analysis of medium access control mechanisms-contention, reservation and scheduling-are covered. Mobile IP protocol is presented, and reactive and proactive protocols for routing in ad hoc networks are introduced. The performance of TCP over wireless networks is analyzed. Security in infrastructure and ad hoc networks is addressed. Sensor networks are introduced. Energy management is discussed. The widely used and emerging wireless networking standards are reviewed. Hardware laboratory assignments provide hands-on experience and OPNET projects allow simulation of large scale networks to complement the theory presented in the course. PREREQUISITE: EC3850 or consent of instructor.

 EC4950: Emerging Nanotechnology (3-1)

Instructor: T. R. Weatherford

Lectures will concentrate on recent developments and future expectations in nanotechnology for military and space applications. Weekly topics will utilize recently published journal and review articles to examine the state-of-the-art in nanotechnolgies related to electrical engineering such as integrated circuits, sensors, communications, manufacturing technologies, power conversion, and materials. Labs will utilize wafer probe measurements and software visualization of nanostructures. PREREQUISITES: EC3220 or EC4230 or EC4870 or EC2200 with consent of instructor.

 EC4960: Internet Engineering (3-1)

Instructor: J. McEachen

This course examines the optimal design and analysis of interconnected, heterogeneous computer networks, specifically those employed by the US Navy (e.g., IT-21). A common theme throughout will be the confluence of connection-oriented and connectionless data communications and their overarching networking methodologies. The course will focus primarily on the TCT/IP suite. Techniques for segmentation and reassembly, routing, transfer agent placement, error control, throughput analysis, broadcasting, and multicasting will be examined in detail. Performance of common distibuted applications will be analyzed. PREREQUISITES: EC3850

 EC4970: Advanced Topics in Sonar Systems Engineering (3-2)

Instructor: L.J. Ziomek

This course is devoted to advanced topics in sonar systems engineering, with emphasis on topics relevant to active sonar systems. A partial list of topics include: time- compression/time-stretch factor, signal-to-interference ratio (SIR), generalized ambiguity function, modeling reverberation, target strength and target scattering cross section, time-bandwidth product, etc. PREREQUISITE: EC4450.

 EC4980: MTI and Pulsed Doppler Radar (3-0)

Instructor: D.C. Schleher

The ability of pulsed Doppler radars to detect moving targets provides a critical function for the operation of modern radars. Military applications range from the detection of low flying aircraft or missiles from surface- based radar to airborne applications such as AWACS, JOINT STARS, airborne early warning (AEW, and airborne intercept (AL) radars which involve looking down into a heavy surface clutter environment. This course reviews the operating principles and signal processing functions associated with systems employing the Doppler effect to detect targets. The characteristics of radar clutter, MTI filters, PD filter banks, and system stability are described. System design performance analysis involving MTI improvement factor and sub-clutter visibility of low, medium, and high PRF systems are covered. Doppler radar operation involving SAR, ISAR, semi-active missile seekers, Doppler weather radar, STAP, and pulse compression radar are included in the course. PREREQUISITES: EC4610 or EO3678 or EO4612 or consent of instructor.
