Özet (Çeviri)
Emitter location finding enables important functionality for both military and civilian applications. GPS is tine most recognized and widely used positioning system, but it is a receiver location system that functions in a markedly different manner from emitter location. Many geo-location techniques predate and have been proposed as an alternative to GPS. Some of the more commonly used and exploited of these techniques are angle of arrival, time of arrival, frequency difference of arrival, and time difference of arrival (TDOA). This thesis is primarily focused on TDOA. These techniques are important for military applications. Location finding is a part of electronic warfare support, which is one of the main braches of electronic warfare. Because these techniques are platform independent, they can be used with any system or platform, such as UAVs, manned aircraft, ground locations, etc. In Turkey it is vitally important for the army conducting search and destroy operations against terrorists to locate emitters associated with these terrorists. The simulation developed in this thesis provides a better understanding of the accuracy of TDOA based geolocation systems. Combinations of receivers and techniques are explored to determine the optimal solutions. The factors of noise and distance have a linear effect on accuracy. The best combination of receivers is determined with consideration to using a combination of fixed and airborne platforms. The best distribution for highest accuracy is determined and discussed.
