Adaptive 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...
متن کاملData Compression Trade-offs for Tdoa/fdoa Geo-location Systems
The research results reported on here focus on new data compression methods that can enable Air Force systems to more rapidly and effectively share data for precision geolocation of RF emitters. The work was focused in four areas: (1) New Theoretical Results: We extend the previous rudimentary insight into how to use data compression to accomplish trade-offs between the sequence of tasks in a l...
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 کاملa study on rate making and required reserves determination in reinsurance market: a simulation
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
Performance Analysis of TDOA and FDOA Location by Differential Calibration with Calibration Sources
—This paper derives the performance equation of the differential calibration algorithm using the time differences of arrival (TDOA) and the frequency differences of arrival (FDOA) with calibration sources when the positions and velocities of the receivers have random errors. By comparing the performance with the Cramér-Rao lower bound (CRLB), it proves that the ability of the differential cali...
