Performance Analysis of Passive Emitter Tracking using TDOA, AOA and FDOA Measurements
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 ...
متن کاملData Compression for Multiple Parameter Estimation with Application to TDOA/FDOA Emitter Location
Because a primary task of multi-sensor systems is to make estimates based on the data collected and shared throughout the sensor system, it is important to design data compression methods that reduce the volume of data to be shared while causing only minimal degradation of the quality of these estimates. An important aspect not specifically considered previously in compression research for sens...
متن کاملPerformance Analysis of Tdoa/fdoa Estimation for Fm Communication Signals
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...
متن کاملRadar Emitter Localization Using TDOA
This paper presents passive radar emitter localization using the Time-Difference-Of-Arrival (TDOA) technique from Unmanned Aerial Vehicles (UAVs) working in conjunction with a fixed/mobile station (such as a shipborne/land-based station) to geolocate a radar emitter to fulfill maritime and littoral area surveillance. Instead of using multiple stationary sensors, multiple TDOA measurements are o...
متن کاملAdaptive Extended Kalman Filter Based Geolocation Using TDOA/FDOA
We propose a moving target tracking algorithm using the measurement signals of time difference of arrival (TDOA) and the frequency difference of arrival (FDOA) in this paper. The geolocation system using TDOA measurement does not have enough accuracy to estimate the position of target. We use both TDOA and FDOA measurement signals to estimate the target location and target’s velocity at discret...
