Book Description
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.

Book Description
This report evaluates superresolution direction finding methods for land tactical narrowband very high frequency/ultrahigh frequency purposes. The DF methods are described and evaluated in depth using a common theoretical framework beginning with classical methods and ending with modern day eigenanalysis based methods. Based on this analysis, superresolution methods can be described in terms of a five step procedure where each step has a unique purpose the estimation process. Different methods vary according to the operations performed at each step. This is useful in analyzing and comparing the theoretical performance of various DF methods under the same conditions. The results from simulations are also included to support the theoretical evaluations.

Book Description
The objective of this thesis is to investigate and evaluate the effectiveness of modern estimation methods with different array geometries as they apply to the problem of bearing estimation. The algorithms were selected from those that apply to multidimensional direction finding, and include MUSIC, PHD, minimum norm, and Capon's beam-former. These four techniques based on their high resolution capability, and their ability to deal with three-dimensional non-uniform arrays and to estimate both azimuth and elevation angle of arrival (AQA). Computer simulations were run linear arrays, circular array, and combinations of the two. The test conditions included: (1) two closely spaced emitters, and (2) various levels of additive white Gaussian noise.
