This thesis describes the implementation of an ELINT algorithm for the detection and classification of Low Probability of Intercept (LPI) signals. The algorithm was coded in the C programming language and executed on a Field Programmable Gate Array based reconfigurable computer; the SRC-6 manufactured by SRC Computers, Inc. Specifically, this thesis focuses on the preprocessing stage of an LPI signal processing algorithm. This stage receives a detected signal that has been run through a Quadrature Mirror Filter Bank and outputs the preprocessed signal for classification by a neural network. A major value of this study comes from comparing the performance of the reconfigurable computer to that of supercomputers and embedded systems that are currently used to solve the signal processing needs of the United States Navy. / US Navy (USN) author.

In order to develop recommendations for management of hydrilla at Ross Barnett Reservoir, Mississippi a number of techniques were utilized. Point intercept surveys were conducted within known hydrilla sites at Ross Barnett Reservoir, Mississippi in order to quantitatively assess chemical management for hydrilla control. Hydrilla tuber data were also collected during the winter and spring of 2012 and 2013. Tuber data were compared between the Ross Barnett Reservoir and Tennessee-Tombigbee Waterway in order to see the effects of chemical management on hydrilla tuber bank dynamics. Water exchange data were collected using Rhodamine WT dye at Ross Barnett Reservoir, Mississippi to determine water exchange characteristics. Dye half-life varied between the eight plots, with a minimum estimated half-life of 2.0 hours and maximum estimated half-life of 30.9 hours. Herbicide evaluations showed that bispyribac-sodium, penoxsulam, and fluridone provide the best hydrilla control 12 weeks after treatment.

An increasing number of LPI radars are integrated into integrated air defense systems (IADS) and modern platforms and weapons, such as anti-ship missiles, and littoral weapon systems. These LPI radars create a requirement for modern armed forces to develop new techniques, strategies, and equipment. The primary objective of this thesis is to investigate methods and means to counter LPI radar threats integrated into a modern platforms and weapons and focus on the related techniques, strategies, and technology. To accomplish this objective both platform centric and network centric approaches will be examined thoroughly.

<p>An OpenGL applications usually renders to a single frame. Multi-view or 3D displays on the other hand, needs more more images representing different viewing directions on the same scene, but modifying a large number of applications would be unsuitable and problematic. However, intercepting and modifying these calls before they reach the GPU would dramatically decrease the amount of work needed to support a large number of applications on a new type of multi-view or 3D display. This thesis describes different ways on intercepting, enqueueing and replaying these calls to support rendering form different view points. Intercepting with both an own implementation of opengl32.dll and an OpenGL driver is discussed, and enqueueing using classes, function pointers and enumeration of functions is tried. The different techniques are discussed quickly with the focus being a working implementation. This resulting in an fully blown OpenGL interceptor with the ability to enqueue and replay a frame multiple times while modifying parameters such as the projection matrix. This implementation uses an own implementation of opengl32.dll that is placed in the application directory to be loaded before the real one. Enqueueing is performed by enumerating all OpenGL calls, pushing this enumeration value and all call data to a list Replaying is done by reading the same list and calling the function pointer associated with the enumeration value with the data in the list.</p>

This dissertation explores high-speed silicon-germanium (SiGe) heterojunction bipolar transistor (HBT) bipolar complementary metal oxide semiconductor (BiCMOS) circuits for next-generation ground- and space-based millimeter-wave (MMW >= 30 GHz) communication front-ends and X-band (8 to 12 GHz) radar (radio detection and ranging) modules. The requirements of next-generation transceivers, for both radar and communication applications, are low power, small size, light weight, low cost, high performance, and high reliability. For this purpose, the high-speed circuits that satisfy the demanding specifications of next-generation transceivers are implemented in SiGe HBT BiCMOS technology, and the device-circuit interactions of SiGe HBTs to transceiver building blocks for performance optimization and radiation tolerance are investigated. For X-band radar module components, the dissertation covers: (1) The design of an ultra-low-noise X-band SiGe HBT low-noise-amplifier (LNA). (2) The design of low-loss shunt and series/shunt X-band Si CMOS single-pole double-throw (SPDT) switches. (3) The design of a low-power X-band SiGe HBT LNA for near-space radar applications. For MMW communication front-end circuits, the dissertation covers: (4) The design of an inductorless SiGe HBT ring oscillator for MMW operation. (5) The study of emitter scaling and device biasing on MMW SiGe HBT voltage-controlled oscillator (VCO) performance. (6) The study of proton radiation on MMW SiGe HBT transceiver building blocks.
