Improvement of DOA Estimation based on Lanczos Algorithm [PDF]
Engineering and Technology Journal, 2014 In this paper, the problem of estimating the Direction Of Arrival (DOA) is presented. DOA based on Eigen Vector Decomposition (EVD) shows that the computational complexities are costly and high so that eigen structure algorithms suffer for limited ...

No‐search algorithm for direction of arrival estimation [PDF]
Radio Science, 2009 Direction of arrival estimation (DOA) is an important problem in ionospheric research and electromagnetics as well as many other fields. When superresolution techniques are used, a computationally expensive search should be performed in general. In this paper, a no‐search algorithm is presented.

Single Transmitter Direction Finding Using a Single Moving Omnidirectional Antenna
Sensors, 2022 Traditional direction-finding systems are based on processing the outputs of multiple spatially separated antennas. The impinging signal Angle-of-Arrival (AOA) is estimated using the relative phase and amplitude of the multiple outputs that are sampled ...

Amplitude Only Direction of Arrival Estimation
2023 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC), 2023 In this manuscript, we present a novel hardware concept for the estimation of the direction of arrival of electro-magnetic signals. An arrangement of two patch antenna arrays, tilted with respect to each other, is used to create a monotonic relationship between the DoA and the received power difference between both arrays.

Direction finding for an extended target with possibly non-symmetric spatial spectrum [PDF]
, 2004 We consider the problem of estimating the direction of arrival (DOA) of an extended target in radar array processing. Two algorithms are proposed that do not assume that the power azimuthal distribution of the scatterers is symmetric with respect to the ...

A Single-Site Vehicle Positioning Method in the Rectangular Tunnel Environment
Remote Sensing, 2023 Due to the satellite signals are blocked, it is difficult to obtain the vehicle position in the tunnels. We propose a single-site vehicle localization scheme for the rectangular tunnel environment, where most satellite-based positioning methods can not ...
