This paper investigates passive emitter tracking using a combination of Time Difference of Arrival (TDOA) measurements with further different types of measurements. The measurements are gained by exploiting the signal impinging from an unknown moving emitter. First, a combined set of TDOA and Angle of Arrival (AOA) measurements is processed using the Maximum Likelihood Estimator (MLE). Then, a ...

Time difference of arrival (TDOA) technology has been widely used in positioning and navigation system recently. The position estimation of a source through determining time difference of arrival (TDOA) of its signal among distributed sensors has many applications in civil as well as in the military. According to civil aspect, in mobile communication is widely used TDOA to perform location of c...

A study on emitter localization using time difference of arrival (TDOA) and frequency difference of arrival (FDOA) measurements has been increased recently. A TDOA/FDOA system generally consists of two parts: TDOA/FDOA estimation from the unknown received signal (extraction part) and position estimation of the emitter (localization part). Thus, it is important to accurately estimate TDOA and FD...

This paper describes an application of a dual satellite geolocation (DSG) system on identifying and locating the unknown source of uplink sweeping interference. The geolocation system integrates the method of joint time difference of arrival (TDOA) and frequency difference of arrival (FDOA) with ephemeris correction technique which successfully demonstrated high accuracy in interference source ...

This paper presents a newly proposed asynchronous time difference of arrival (A-TDOA) positioning system. Two major challenges for accurate location finding in indoor environments are the fine time resolution and high accuracy time synchronization. This paper proposes a new positioning method that resolves the time synchronization difficulty by measuring the time difference of arrival at a sing...

In low-power and high-density real time locating systems, time difference of arrival (TDOA) technique outperforms other ranging techniques. The realization of TDOA-based high resolution indoor localization directly depends on the performance of clock synchronization. In this paper, we introduce a clock synchronization method based on the Kalman filter. The updated clock skew from the Kalman fil...
