Location Fixing by 3 DF Stations using Triangulation Method
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2012, Vol 1, Issue 3
Abstract
One of the most important requirements placed on EW (Electronic Warfare) systems is the location of threat emitters. The paper deals with the location of an object at unknown position, on which bearings are taken from two or more DF (Direction Finding) stations whose positions are known. These provide solutions to the most probable position of the object and how far from the true position is the position indicated by the “fix” likely to be? The objective of this analytical study is to develop an optimal emitter location in latitude/longitude coordinates using maximum likelihood of stansfield technique. Diagrams are given to show the results of applying the theory to typical practical cases. It is shown that, subject to certain qualifications, reliability of a fix does not depend on the size of the particular “cocked hat” from which it is derived. It is proposed that the reciprocal of the rootmean-square error expected in the position of the fix should be adopted as the conventional standard quantity for measuring the reliability of a fix. Simulation results verify the predicted theoretical performance.
