3D TDOA Geolocation

Thursday, March 08, 2018 14:00 until 15:00 EST

 

ABOUT

TDOA (Time Difference of Arrival) geolocation, also known as multilateration, is a well-known and highly effective technique for accurate localization and tracking of RF emitters. The technique is employed widely in EW applications including locating enemies in the battlefield. It is also used to locate sources of interference in test and training scenarios. Most of these applications have traditionally been restricted to 2D TDOA where sensors and targets are ground-based.

The growing threat from UAVs has prompted an increased interest in techniques to geolocate emitters in three dimensions. TDOA techniques can be adapted for this purpose. Emerging threats are not restricted to high-end military UAVs in the battlefield. The use of commercial small UAV (sUAV) or drones is growing exponentially with ever increasing concerns for unintentional intrusion into secure military facilities, deliberate intrusion to create nuisance or conduct surveillance, interference with commercial and general aviation aircraft, and the use of low cost commercial drones to carry explosives.

3D TDOA geolocation techniques have been demonstrated and are highly effective for a range of airborne emitters ranging from small low flying drones to high speed, high altitude aircraft. The technique has demonstrated the ability to be accurate, provide fast updates, and include simultaneous tracking of multiple air vehicles. In this presentation, 3D TDOA technology will be described and real world results presented that demonstrate the potential for countering both ground-based and airborne threats. Simulations will be presented discussing how sensor placement affects system geolocation accuracy, including the effect of adding airborne and mobile sensors.
