A high frequency radiolocation experiment involving a transmitter near Houston, Texas and a receiver near Urbana, Illinois has been under progress on a continuous basis for one week per month since March 1967. A network of five vertical incidence ionosondes located near and around the midpoint of the great circle path permit the evaluation of electron density gradients along the propagation path from true height analysis of ionograms recorded by this network. These gradients are used in conjunction with a three dimensional ray tracing computer program to compute the expected directions of arrival of the radio waves. Changes in bearing resulted from temporal variations in the electron density distribution and seasonal variations in the sunrise tilts are investigated. The results obtained by ray tracing are found to be in excellent agreement with the measured bearing deviations. Effective layer tilts are computed from the results of ray tracing. (Author).

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.

Direction-of-Arrival (DOA) estimation concerns the estimation of direction finding signals in the form of electromagnetic or acoustic waves, impinging on a sensor or antenna array. DOA estimation is used for locating and tracking signal sources in both civilian and military applications. This authoritative volume provides an overview and performance analysis of the basic DOA algorithms, including comparisons between the various types.The book offers you a detailed understanding of the arrays pertinent to DOA finding, and presents a detailed illustration of the ESPRIT-based DOA algorithms complete with their performance assessments. From antennas and array receiving systems, to advanced topics on DOA estimation, this book serves as a one-stop resource for professionals and students. Nearly 100 illustrations and more than 281 equations support key topics throughout.
