Performance 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 کاملReverberation-Robust One-Bit TDOA Based Moving Source Localization for Automatic Camera Steering
We address the problem of moving acoustic source localization and automatic camera steering using one-bit measurement of the time-difference of arrival (TDOA) between two microphones in a given array. Given that the camera has a finite field of view (FoV), an algorithm with a coarse estimate of the source location would suffice for the purpose. We use a microphone array and develop an algorithm...
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...
متن کاملA moving sound source localization method based on TDOA
The Time Difference of Arrival (TDOA) method has been widely used for sound source localization. However, because of the Doppler-effect, the TDOA method cannot be directly used for locating moving sound sources. This paper develops a moving sound source localization method based on TDOA, combining with Doppler-effect elimination and source plane scanning. This method is suitable for locating so...
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...
