IET 11th International Conference on Ionospheric Radio Systems and Techniques (IRST 2009).
In this paper, we present the development of the Automatic Single-Station Location (ASSL) software for high frequency direction finding systems under consideration by Ebor Computing. The aim of the proposed development is to demonstrate the capabilit

The Battle of the Atlantic was one of the most protracted and vital episodes of the Second World War; and, more than any other, it was won largely by electronic technology. The author describes the radio system used by German U-boats and how the mess

Proceedings of MILCOM '93 - IEEE Military Communications Conference.
The authors present experimental results concerning the application of modern parametric direction-finding (DF) methods to high-frequency (HF) signals. HF is challenging since the long wavelength typically implies a small electrical aperture (for rea

IEE Colloquium on Propagation Characteristics and Related System Techniques for Beyond Line-of Sight Radio.
The performance of high frequency direction finding systems is known to be related to the mode content of the incoming signal and to the frequency of operation, both of which depend on the electron density distribution in the ionosphere. Due to tilts

The release of additional wartime information in the mid-1970s resulted in a re-evaluation of some aspects of the Battle of the Atlantic, one outcome of which has been an increased emphasis on the part played by HF DF, installed both in convoy escort
