Influence of frequency, direction finder parameters and actual terrain topography on features of Kogan-Pavliouk location templates

Influences of frequency, direction finder parameters and actual terrain topography on features of location accuracy templates, also known as Kogan-Pavliouk location templates, are considered. The template shows a distribution of accuracy of source of emission location, obtained by a triangulation operation using at least two separated DF-s, throughout an overall location service area. This location service area is a part of common FD service area of a group of DF stations. It is demonstrated that location is the most limited function in comparison with other monitoring functions such as listening, emission parameters measurements and direction finding because at least two individual direction finders should be involved to provide location by triangulation operation. This function is also the most influenced by various instrumental and operational factors as well as by actual terrain topography. These features are illustrated by results of exact calculations.
