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 ...

Robust prior-based Direction of Arrival estimation
2012 IEEE Statistical Signal Processing Workshop (SSP), 2012 In certain Direction of Arrival (DOA) scenarios some of the sources are approximately known a priori. It is then desirable to be able to exploit this prior knowledge when estimating the DOAs of the unknown sources. In this paper we modify an estimator utilizing exact angular prior knowledge of some sources such that the estimator is able to exploit ...

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.

Arrival Directions of the Most Energetic Cosmic Rays [PDF]
Physical Review Letters, 1995 In this Letter we examine the arrival directions of the most energetic cosmic rays (E > 2 * 10^19 eV) detected by several air shower experiments. We find that data taken by different air shower arrays show positive correlations, indicating a non--uniform arrival direction distribution.
