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.
