A 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 کاملTDOA denoising for acoustic source localization
In this manuscript, we formulate the problem of denoising Time Differences of Arrival (TDOAs) in the TDOA space, i.e. the Euclidean space spanned by TDOA measurements. The method consists of pre-processing the TDOAs with the purpose of reducing the measurement noise. The complete set of TDOAs (i.e., TDOAs computed at all microphone pairs) is known to form a redundant set, which lies on a linear...
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 کاملIndoor Localization using TDOA technique
The system which we propose to demonstrate for indoor localization competition is based on Time difference of arrival(TDOA) technique.Using our custom made hardware we could achieve localization of a mobile node by distance estimation from beacon nodes by using time difference of arrival between RF and ultrasonic signals and subsequent lateration operation. We also have developed a system for a...
متن کاملClock Offsets in TDOA Localization
Time based TDOA localization systems require time or clock synchronization between receivers such as cellular base stations, satellites, and sensor nodes. Imperfection of time synchronization causes degradation in positioning accuracy. However if we know about its characteristics and how to estimate the clock offsets, the localization system can be properly calibrated to provide good quality of...
