A Hybrid AOA and TDOA-Based Localization Method Using Only Two Stations
International Journal of Antennas and Propagation, 2021 Target localization plays an important role in the application of radar, sonar, and wireless sensor networks. In order to improve the localization performance using only two stations, a hybrid localization method based on angle of arrival (AOA) and time ...

ANGLE: ANGular Location Estimation Algorithms
IEEE Access, 2020 In this paper, we present two localization algorithms that exploit the Angle of Arrival (AoA) parameters of the received signal. The proposed ANGular Location Estimation (ANGLE) algorithms utilize a probabilistic model to describe the angular response of

Hybrid TOA/AOA Positioning Algorithm Based on GDOP Weighting [PDF]
Jisuanji gongcheng, 2017 Existing Time of Arrival/Angle of Arrival(TOA/AOA) positioning algorithms based on Wireless Sensor Network(WSN) have low accuracy under the condition that the position of Anchor Nodes(AN) has error.

Estimating Angle of Arrival (AoA) of multiple Echoes in a Steering Vector Space
, 2021 Consider a microphone array, such as those present in Amazon Echos, conference phones, or self-driving cars. One of the goals of these arrays is to decode the angles in which acoustic signals arrive at them. This paper considers the problem of estimating K angle of arrivals (AoA), i.e., the direct path's AoA and the AoA of subsequent echoes ...

Optimal Precoders for Tracking the AoD and AoA of a mm-Wave Path [PDF]
, 2018 In millimeter-wave channels, most of the received energy is carried by a few paths. Traditional precoders sweep the angle-of-departure (AoD) and angle-of-arrival (AoA) space with directional precoders to identify directions with largest power.

Optimized hybrid localisation with cooperation in wireless sensor networks [PDF]
, 2017 In this study, the authors introduce a novel hybrid cooperative localisation scheme when both distance and angle measurements are available. Two linear least squares (LLS) hybrid cooperative schemes based on angle of arrival–time of arrival (AoA–ToA) and

3D moving target tracking with measurement fusion of TDoA/FDoA/AoA
ICT Express, 2019 In this paper, we investigate the tracking of the 3D moving target when multiple measurements are available. We propose a particle filter-based 3D target tracking algorithm with measurement of time difference of arrival (TDoA), frequency difference of ...

3D angle-of-arrival positioning using von Mises-Fisher distribution [PDF]
, 2017 We propose modeling an angle-of-arrival (AOA) positioning measurement as a von Mises-Fisher (VMF) distributed unit vector instead of the conventional normally distributed azimuth and elevation measurements.

Iterative Regression Based Hybrid Localization for Wireless Sensor Networks
Sensors, 2021 Among various localization methods, a localization method that uses a radio frequency signal-based wireless sensor network has been widely applied due to its robustness against noise factors and few limits on installation location.
