Location errors in time of arrival (TOA) and time difference of arrival (TDOA) systems [PDF]
, 1977 It is shown that the covariance matrix of object location errors is identical for time of arrival (TOA) and time difference of arrival (TDOA) systems if the inverse of the covariance matrix of TOA (TDOA) errors is used as a weighting matrix. Also, with this weighting the location errors statistics do not depend on the particular difference pairs in the

A Novel Joint TDOA/FDOA Passive Localization Scheme Using Interval Intersection Algorithm
Information, 2021 Due to the large measurement error in the practical non-cooperative scene, the passive localization algorithms based on traditional numerical calculation using time difference of arrival (TDOA) and frequency difference of arrival (FDOA) often have no ...

3D TDOA Emitter Localization Using Conic Approximation
Sensors, 2023 This paper develops a new time difference of arrival (TDOA) emitter localization algorithm in the 3D space, employing conic approximations of hyperboloids associated with TDOA measurements. TDOA measurements are first converted to 1D angle of arrival (1D-

Sound Event Detection Using Spatial Features and Convolutional Recurrent Neural Network [PDF]
, 2017 This paper proposes to use low-level spatial features extracted from multichannel audio for sound event detection. We extend the convolutional recurrent neural network to handle more than one type of these multichannel features by learning from each of ...

Detecting of Gunshots Direction Using TDOA (Time Difference of Arrival)
Emitor: Jurnal Teknik ElektroIn order to avoid shots being fired in undesirable areas, a device is required that can detect the origin of the shot so that the source of the bullet can be identified. This research was conducted to maintain the security and stability of a region.

Multi-Array 5G V2V Relative Positioning: Performance Bounds
, 2019 We study the performance bounds of vehicle-to-vehicle (V2V) relative positioning for vehicles with multiple antenna arrays. The Cram\'{e}r-Rao bound for the estimation of the relative position and the orientation of the Tx vehicle is derived, when angle ...
