Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of accomplishing high frequency direction finding against short duration (100-1000 ms) HF skywave signals using narrow aperture antennas is investigated. Two statistical procedures for estimating the signal bearing are proposed and compared. These procedures employ time averaging to reduce the large instantaneous bearing error caused by the phase and amplitude distortion of the wavefront due to scattering and multipath interference. Results are presented using data collected with the Southwest Research Institute Coaxial Spaced Loop HFDF system. It is shown that for a limited sample of data from this system the standard deviation of the bearing estimate for a 200 ms signal varied from 15 to 59 degrees. (Author).

Book Synopsis Methods for Direction-Finding of Direct-Sequence Spread-Spectrum Signals by : Magnus Finne
Download or read book Methods for Direction-Finding of Direct-Sequence Spread-Spectrum Signals written by Magnus Finne and published by DIANE Publishing. This book was released on 1996 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of spread-spectrum signals has increased dramatically in military radio communications. This report locates methods for direction-finding direct-sequence spread-spectrum (DS/SS) signals; digital methods are of special interest. A literature survey was conducted to see if there are any known methods. Investigated if a DS/SS detection method using a square-law detector can be extended to direction-finding. By use of computer simulations, show the performance of the methods found. Benefits and problems are also discussed.

Book Synopsis Masters Theses in the Pure and Applied Sciences by : W. H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by W. H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing. house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 25 (thesis year 1980) a total of 10,308 theses titles from 27 Canadian and 214 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 25 reports theses submitted in 1980, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Book Synopsis Radio Direction Finding and Superresolution by : P. J. D. Gething
Download or read book Radio Direction Finding and Superresolution written by P. J. D. Gething and published by IET. This book was released on 1991 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enlarged and revised second edition. Modern direction finders, capable of measuring elevation angles as well as azimuth angles on the components of multi-ray wavefields, have become powerful tools for research in ionospheric physics and HF radio propagation. The complexity of the problem of resolving closely-spaced rays requires the combined use of wide aperture antenna arrays, multichannel receiving systems and sophisticated digital processing techniques.
