This book was released on 2012-07-18 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describing an innovative approach to phased-array control in antenna design This book explores in detail phased-array antennas that use coupled-oscillator arrays, an arrangement featuring a remarkably simple beam steering control system and a major reduction in complexity compared with traditional methods of phased-array control. It brings together in one convenient, self-contained volume the many salient research results obtained over the past ten to fifteen years in laboratories around the world, including the California Institute of Technology's Jet Propulsion Laboratory. The authors examine the underlying theoretical framework of coupled-oscillator systems, clearly explaining the linear and nonlinear formalisms used in the development of coupled-oscillator arrays, while introducing a variety of state-of-the-art methodologies, design solutions, and tools for applying this control scheme. Readers will find: Numerous implementation examples of coupled-oscillator array prototypes A continuum model that permits application of diffusion theory to the analysis of phase dynamics A demonstration of the array behavior through experimental results that validate the linearized theory Examples of how incorporating coupling delay restores causality, including the latest published results Guidance on how to accurately analyze and optimize coupled-oscillator arrays using modern simulation tools A review of current developments, including the design of compact couple-oscillator array antennas Complete with 150 diagrams and photographs, Coupled-Oscillator Based Active-Array Antennas is a highly useful tutorial for antenna designers and a valuable reference for researchers and engineers wishing to learn about this cutting-edge technology.

This book was released on 2009 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phased arrays have many applications such as Radar Communication, Satellite Communication, and Wireless Local Area Networks (WLAN). For the traditional phased array, a phase shifter is used with each antenna element to establish a constant phase progression along the antenna array. A constant phase progression will force the electromagnetic wave to add up so that the energy would radiate at a particular angle with respect to the array. However, it is difficult to integrate the bulky phase-shifters in the monolithic module, especially when the application involves a large number of elements. This dissertation studies an alternative phase beam-scanning technique using arrays of coupled oscillators (COA), which avoids the use of phase shifters. This technique of COA may reduce the complexity of phase control circuits and provide for a phased array of lower volume and weight. Consequently, it simplifies the architecture of the T/R module and reduces the overall cost. In this work, dynamic equations of the nonlinear COA with arbitrary coupling networks are derived using both time and frequency domain methods. From the dynamic analysis, it is shown that the phase distribution along the array, and hence the beam scanning angle of the array, can be controlled by free running frequencies of the coupled oscillators. The stability and nonlinear behaviors of synchronized coupled oscillators are studied via the nonlinear control theory and applied to radar beam scanning arrays. Analysis indicates that a stable, unique equilibrium point exists when choosing a specific set of free running frequencies, and it is associated with the desired phase shift but within a given range. By means of previous dynamic analysis, effects of amplitude dynamics are studied for COAs with uniform, triangular and Chebyshev amplitude distributions. The array with different coupling strengths, nonlinear parameters, and synchronization frequencies are considered. Results demonstrate that beam shapes and SLLs can be controlled for the coupled oscillator array using strong coupling. The influence of the random, free-running frequency distribution of the phase error in COAs, which causes the phase shift error and hence the error of main beam scanning angle (EMBSA), is also investigated through a Monte Carlo analysis. It is found that strongly COAs are more robust than weakly COAs under the same level of randomness in free running frequencies. Furthermore, when random deviations become larger, the robustness of strongly COA is especially obvious.

Book excerpt: DEEP SPACE COMMUNICATIONS A COLLECTION OF SOME OF THE JET PROPULSION LABORATORY’S SPACE MISSIONS SELECTED TO REPRESENT THE PLANETARY COMMUNICATIONS DESIGNS FOR A PROGRESSION OF VARIOUS TYPES OF MISSIONS The text uses a case study approach to show the communications link performance resulting from the planetary communications design developed by the Jet Propulsion Laboratory (JPL). This is accomplished through the description of the design and performance of six representative planetary missions. These six cases illustrate progression through time of the communications system’s capabilities and performance from 1970s technology to the most recent missions. The six missions discussed in this book span the Voyager for fly-bys in the 1970s, Galileo for orbiters in the 1980s, Deep Space 1 for the 1990s, Mars Reconnaissance Orbiter (MRO) for planetary orbiters, Mars Exploration Rover (MER) for planetary rovers in the 2000s, and the MSL rover in the 2010s.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel on-chip antenna design technique is presented to isolate the antenna from the lossy silicon substrate thus increasing the antenna gain and radiation efficiency at mm-wave frequencies. The active-integrated antenna, which includes an on-chip dipole antenna, a voltage controlled oscillator (VCO), and injection-locking networks, is designed as a basic element of the coupled-oscillator array system. Finally, a two-element COAA with non-reciprocal coupling is presented for beam scanning applications. The COAA consists of two AIAs and a non-reciprocal coupling network (NRCN). The NRCN provides adjustable coupling gain and coupling phase between adjacent AIAs. This new topology overcomes several of the problems with this class of beam scanning arrays discussed in the literature.

Book excerpt: This book focuses on modelling and simulation, control and optimization, signal processing, and forecasting in selected nonlinear dynamical systems, presenting both literature reviews and novel concepts. It develops analytical or numerical approaches, which are simple to use, robust, stable, flexible and universally applicable to the analysis of complex nonlinear dynamical systems. As such it addresses key challenges are addressed, e.g. efficient handling of time-varying dynamics, efficient design, faster numerical computations, robustness, stability and convergence of algorithms. The book provides a series of contributions discussing either the design or analysis of complex systems in sciences and engineering, and the concepts developed involve nonlinear dynamics, synchronization, optimization, machine learning, and forecasting. Both theoretical and practical aspects of diverse areas are investigated, specifically neurocomputing, transportation engineering, theoretical electrical engineering, signal processing, communications engineering, and computational intelligence.
