Abstract
An important resource for Signal Intelligence activity in High Frequency Direction Finding (HFDF) is the use of Single Site Location (SSL) systems. Present research and development is aimed at developing tactical, mobile, easy to deploy SSL systems for locating hostile HF transmitters. These systems can detect, determine azimuth and elevation angles of incoming signals, and using ionospheric height information can calculate emitter location. The success or failure of SSL systems is dependent on many different factors, some of which are associated with site effects. System operation over different ground parameters can affect the accuracy of locating emitters. In this thesis, the performance of an 'X' shaped interferometer HF SSL system is examined using the Numerical Electromagnetics Code (NEC). Performance in the presence of two different types of lossy ground conditions are investigated. .
