Book Synopsis Study of Application of Antenna Optimization Techniques by : G. O. Young
Download or read book Study of Application of Antenna Optimization Techniques written by G. O. Young and published by . This book was released on 1967 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research dealt with decision theoretic antenna processing systems and the development and application of a new coherence theory to optimum antenna system design. The objective was the development of techniques that would result in improved target parameter estimates and better detection and resolution capability than those achieved by conventional systems. A new theory was developed, called transcoherence theory. It can be used to determine the optimum amplitude and/or phase shading for an antenna that is intended as an information-gathering device. It is particularly useful when employed for the purpose of compensating for deleterious medium effects. The theory can also be used to find the coherence properties of sources, where these properties are essential to the specification of the a priori statistics of target signals and clutter. A relatively simple decision theoretic processor was built and found to improve angular resolution by at least a factor of four over that of conventional systems. The research studies and their results are documented in seven scientific reports and several papers. (Author).

This book was released on 2007 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new global optimization technique using Taguchi's method and its applications in electromagnetics and antenna engineering. Compared with traditional optimization techniques, Taguchi's optimization method is easy to implement and very efficient in reaching optimum solutions. Taguchi's optimization method is developed based on the orthogonal array (OA) concept, which offers a systematic and efficient way to select design parameters. The book illustrates the basic implementation procedure of Taguchi's optimization method and discusses various advanced techniques for performance improvement. In addition, the integration of Taguchi's optimization method with commercial electromagnetics software is introduced in the book. The proposed optimization method is used in various linear antenna arrays, microstrip filters, and ultra-wideband antenna designs. Successful examples include linear antenna array with a null controlled pattern, linear antenna array with a sector beam, linear antenna array with reduced side lobe levels, microstrip band stop filter, microstrip band pass filter, coplanar waveguide band stop filter, coplanar ultra-wide band antenna, and ultra-wide band antenna with band notch feature. Satisfactory results obtained from the design process demonstrate the validity and efficiency of the proposed Taguchi's optimization method.

Book Synopsis Antenna Optimization Study on Stryker Vehicle Using FDTD Technique by :
Download or read book Antenna Optimization Study on Stryker Vehicle Using FDTD Technique written by and published by . This book was released on 2004 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this antenna optimization study is to perform antenna placement optimization for the Blue Force Tracking (BFT), Iridium, and International Maritime Satellite (INMARSAT) antennas on the proposed Mounted Battle Command On The Move (MBCOTM) Stryker system. The MBCOTM Stryker system uses the Stryker Command Vehicle (CV) as its baseline. Engineering analysis of the Stryker CV points out a number of challenges with the antenna integration. First and foremost, the BFT, INMARSAT, and Iridium share the same operational frequency bands. This presents a large potential for co-site interference on the Stryker platform. A second challenge is the degradation of antenna performance when located in close proximity to large metallic obstructions such as the weapon, hatch covers, ammo boxes and other antennas. Without proper antenna placement, these obstructions can have a significant impact on the antenna gain (Fig1,2). To optimize these communication systems on the MBCOTM Stryker system, this study will evaluate the current (baseline) antenna placements for both co-site interference and antenna gain. This study will also develop and evaluate an alternate configuration with the objective of increased antenna gain pattern performance and decreased co-site interference. This study uses Computational Electromagnetic Modeling (CEM), specifically the Finite Difference Time Domain (FDTD) method, to model and simulate effects of antenna placement on the Stryker. The traditional design method for antenna placement was based solely on engineering experience and empirical test data. CEM provides many additional measurable statistics to evaluate antenna placements. This study integrates CEM analysis and statistics into the traditional design method to optimize antenna performance.

Available in PDF, EPUB and Kindle. Book excerpt: Swarm intelligence algorithms are a form of nature-based optimization algorithms. Their main inspiration is the cooperative behavior of animals within specific communities. This can be described as simple behaviors of individuals along with the mechanisms for sharing knowledge between them, resulting in the complex behavior of the entire community. Examples of such behavior can be found in ant colonies, bee swarms, schools of fish or bird flocks. Swarm intelligence algorithms are used to solve difficult optimization problems for which there are no exact solving methods or the use of such methods is impossible, e.g. due to unacceptable computational time. This set comprises two volumes: Swarm Intelligence Algorithms: A Tutorial and Swarm Intelligence Algorithms: Modifications and Applications. The first volume thoroughly presents the basics of 24 algorithms selected from the entire family of swarm intelligence algorithms. It contains a detailed explanation of how each algorithm works, along with relevant program codes in Matlab and the C ++ programming language, as well as numerical examples illustrating step-by-step how individual algorithms work. The second volume describes selected modifications of these algorithms and presents their practical applications.
